Q1. What are LED?

LED are light emitting diodes. They are semi-conductor devices which convert electric energy to produce visible light. They produce light very efficiently due to which they are becoming replacement of conventional lighting sources.

Q2. How is LED lighting different than other light sources, such as incandescent and CFL?

LED lighting differs from incandescent and compact fluorescent lighting in several ways. When designed well, LED lighting can be more efficient, durable, versatile and longer lasting.

Q3. Why do LEDs have a higher initial cost than conventional light sources?

LED’s are made up of electric diodes and other components which has metals like sapphire, gallium, silicon, ceramic which add to overall costs.

Q4. What is Lumen?

It is a measure of the total quantity of visible light emitted by a source. It’s symbol is lm.

Q5. What is efficacy of light bulbs?

Efficacy is the ratio of light output from a lamp to the electric power it consumes and is measured in lumens per watt (LPW).

Q6. Do Led bulbs attract bugs?

Bugs are attracted to UV rays to navigate and select mates, LED bulbs do not have UV content thus they do not attract many bugs.

Q7. How efficient are Remen led Lites compared to incandescent bulbs & How?

The efficacy of the Remen led bulbs is five times higher than as compared to incandescent bulbs.

In other words, Remen led lites bulbs use only about 12% as much electricity to produce the same amount of light. However, because Remen led lites direct a larger percentage of light where it is needed; in many applications they are as much as ten times as effective as incandescent bulbs, reducing energy use by 95%

Q8. Are your products compatible with emergency backup systems?

Yes, with inverter style battery backup systems that produce true sinewave outputs. When sizing Emergency Backup Systems, multiply the nominal power load by 2.5x to determine the size of system needed.

Q9. Explain how Remen Led Lites Lasts up to 15 Years?

Based on how long a fixture is illuminated per day, here’s what 15 years works out to: Hours of Operation: 50,000 hours is: 10 hours per day 14.2 years 12 hours per day 11.4 years 18 hours per day 7.4 years 24 hours a day 5.7 years

What is BIS certified products?

It is a certificate given by Bureau of Indian Standards, called the Standard Mark given to products qualifying certain standards of quality. Remen Led Lites products are BIS certified.

Q10. What is ROHS?

RoHS, also known as Lead-Free, stands for Restriction of Hazardous Substances. RoHS, also known as Directive 2002/95/EC, originated in the European Union and restricts the use of six hazardous materials found in electrical and electronic products.

Q11. Why is the life span of an LED measured as lumen depreciation?

The life span of an LED is vastly longer than that of incandescent, fluorescent or HID lamp sources, generally lasting 50,000 hours or longer. Although the LED never really burns out, product life span is measured by lumen depreciation. The Illuminating Engineering Society’s (IES) current standard for calculating the life of an LED as the point at which the LED reaches 30 percent lumen depreciation. Remember, a 50,000-hour rating is not equivalent to lamp life rating. LED life is rated where it has reached 30 percent lumen depreciation. At 50,000 hours an LED would still be operating, but at a decreased lumen output.

Q12. Is lifespan reduced if the LEDs are frequently turned on and off?

Unlike discharge lamps, LEDs are semiconductors and their life span is not affected by the number of times they are turned on and off.

Q13. How bright are Remen led lites bulbs?

Remen Led bulbs available in different fixtures vary in brightness from 150 lumens up to about 2600 lumens. The brightest led bulbs are floodlight and streetlights.

Q14. Which Remen led bulb is comparable to a standard 40 watt incandescent bulb?

Few led light bulbs with the same size and shape as a standard 40 watt incandescent bulb are comparable in light output. The closest led bulb we have found is our A60 5W High Power REMEN LED bulb.

Q15. Are Remen LED Energy saving bulbs are ugly curly, twisted bulbs that stick out of our light fittings?

No. Those spiral bulbs are CFL bulbs, and they need to be spiral because that is the way fluorescents need to be to work. They need a tube of gas that excites and lights up when electricity is introduced. LED bulbs contain small, solid Light Diodes. No ugly twirls and twists here.

Q16. What types of bases are available in Remen Led Lites?

Remen Led Lites are the perfect retro-fit for your existing light fixtures. We have standard bases, candelabra, standard or edition B22, E14, E27, MR16, GU10, and other typical bases that are common with incandescent and halogen installations.

Q17. Can I put a retrofit in an enclosed or sealed luminaire?

No, the electric retrofit bulb will overheat and lead to a short lifecycle. A better solution is to use an LED module with a remote driver.

Q18. Do I have to replace Remen LED Lites?

Remen LED Lites does not burn out like a standard lamp, so individual diodes do not need to be replaced. Instead, the diodes gradually produce lower output levels over a very long period of time. If one LED fails, it does not produce a complete fixture output.

Q19. What does "cool white" and "warm white" mean, and what is CCT?

The Color Correlated Temperature (CCT) is given in the description of each of our white led bulbs. The color (CCT) of our white bulbs ranges from a warm yellow white (2700K) to a cool blue white (7000K).

Q20. What is the color range of Remen Led Lites?

LED Lites come in a variety of colors (defined by the Kelvin Scale), but we chose the most popular colors for normal home and business use. Typically that is our Cool Day White or Natural White color. LED bulbs have come a long way, and they are not just available in the bluish white color that was the only option with earlier designs Remen Led Lites is available in following colors.

• 2700K-3200K – Warm White
• 6000K-6500K – Cool White

Q21. Why LEDs are considered a GREEN technology?

LEDs are environmentally friendly on many fronts. First, unlike HID (High Intensity Discharge) lamps LEDs contain NO mercury. In addition, some LED luminaries are ROHS (Restriction of Hazardous Substances) compliant and have been designed to provide more than a decade of near maintenance-free service. That means no re-lamping which means no waste. Assuming an HID fixture is re-lamped every two years, that’s five re-lamping cycles over a 10 year period. Just imagine the benefits of choosing LED:

• No concern over proper disposal (hopefully not simply thrown in a landfill) of old HID lamps containing harmful mercury.
• No fuel used and the accompanying pollution to service those fixtures.
• Greatly reduced potential for lane closures and other productivity and inconvenience-related costs associated with maintaining an HID system.
• No natural resources lost to produce the replacement lamps that contain mercury.
• No fuel used to move old-technology lamps from the factory (most likely overseas), to the distributor, to the contractor, to the job site.
It’s important to keep in mind all the positive and powerful ripple effects that using LED technology can have on the environment.

Q22. How LEDs are able to outperform HID?

Super-bright white LEDs have the advantage of minimal lumen depreciation, better optical efficiency and high lumens per watt. LEDs also have a vastly longer life span than traditional lamp sources. The luminaries must be designed to leverage these inherent advantages of LEDs. A Total Systems Approach is needed for an LED product to bring all these features together. Beta LED luminaries also have an environmental advantage in that they contain no mercury, are ROHS compliant, last longer and produce less waste. In fact, 20 to 25% (by weight) of the product is made using post-consumer recycled materials (aluminum castings and extrusions). Furthermore, 70% (by weight) of Beta LED fixtures are readily recyclable. The remaining LED circuit boards, drivers, wires and connectors are all non-hazardous, mercury-free, and ROHS compliant.

Q23. Do Remen Led Lites bulbs produce a lot of heat?

No. Remen Led Lites are extremely energy efficient and convert most of the electricity used into visible light, unlike incandescent bulbs that convert 95% of the electricity consumed into heat. That is why you can replace a 65 watt incandescent bulb with a 8 watt LED bulb. Not only that, but you can’t forget that your cooling bill will also decrease when you use LED light bulbs because LED bulbs produce very little heat. 45 incandescent bulbs (65 watts) when turned on can produce as much as 10,000 btu’s of heat. And in the summer, this adds to the heat to your home, office or business that you then have to offset with air-conditioning. However, LED’s do get warm, and some of our industrial LED lights will get warm as well. However, they are significantly cooler than the HID lights they replace.

Q24. Do Remen Led Lites contain any heavy metals like Mercury as some other energy saving light bulbs do?

No. Remen LED Lites do not contain mercury or any other hazardous metals or chemicals. CFL’s and fluorescent tubes, on the other hand, do. So you don’t have to worry about special disposal procedures when you happen to drop and break an LED bulb (if you can). However, the same can’t be said for CFL and fluorescent tubes if they break.

Q25. How should I dispose of a LED bulb?

LED Bulbs do not contain harmful metals or chemicals, so you can dispose it like a normal incandescent light bulb. However, over 95% of the bulb is recyclable, so we believe that those who are so inclined to buy LED bulbs are also inclined to recycle. However, it is not uncommon for these bulbs to last over 15* years, so it will be a long time before you will have to be concerned about recycling your LED bulbs.

Q26. What sort of guarantee does Remen LED Energy saving Lites come with?

Remen Led Lites come with 2 years manufacturer warranty. Warranties only apply for normal use of bulbs and do not include misuse or usage for which the bulb was not intended to perform.

Q27. What is CRI, and why is it important?

Color Rendering Index (CRI) is defined as a light sources ability to render color. The higher the CRI, the better the light source renders every color in the visible spectrum. To have what is generally considered good color rendering, a source must be >90 CRI.

Q28. What Is CRI for REMEN LED Lites?

CRI for Remen Led Lites is between 80-90.

Q29. Why should I use LEDs? I like the lights I already have.

There are many reasons why businesses and homeowners are switching to LED.
High efficiency: Roughly 80% of the energy used in an incandescent bulb is wasted via heat. 80-90% of energy used in LED lights is used in the generation of light. The term used to describe LEDs minimal heat generation is ‘cold lighting’.
Less Maintenance: LED lights have a significantly higher lifetime. This can range from around 20,000-100,000 hours per luminaries. The costs associated of replacing conventional lamps over 20 times during the lifetime of an LED are quite staggering, especially if maintenance costs are high to start with.
Environmentally Friendly: LEDs do not contain any harmful chemicals or heavy metals. Compact Fluorescent lights contain mercury which is highly toxic. Both incandescent and CFL lights emit a small amount of UV radiation whereas LEDs emit none.
Lesser CO2 Emissions: A large percentage of energy comes from the burning of fossil fuels. This in turn releases greenhouse gases into the atmosphere. Less energy needed to facilitate the use of lights means a decrease in the amount of fossil fuels being burnt. Using LED lights will contribute greatly in reducing your carbon footprint.

Q30. What is the difference between a floodlight and a spotlight?

Led spotlights output a narrower beam of light, typically less than 45 degrees wide. Most of the light from a spotlight is concentrated onto a relatively small area producing a bright spot. Led floodlights output a wider beam of light, up to 120 degrees, so the light from a floodlight is spread out over a much larger area.

Q31. Will the bulbs come on immediately, and will they have to "warm up" to brightness like the older type energy saving bulbs do?

Instant on-instant off. No 2-minute warm up period that is the trademark of CFL bulbs. Also, turning on and off an LED light does not shorten its lifespan.

Q32. What is all involved in replacing a fluorescent tube in a fixture?

Typically, you remove the fluorescent ballast and fluorescent tubes and rewire the fixture. Our internal driver LED Tubes use AC current, and then converts the power to DC within the internal LED driver to light the LED’s. There are some tubes that can be driven from the fluorescent ballast, but we do not supply those tubes as we see fluorescent ballasts as a maintenance item. Ballasts consume about 4+ watts per fluorescent tube installed, so leaving the ballast in place reduces the energy savings as well.

We also can supply externally driven LED tubes. With these tubes, the driver is externally housed outside the tube, and is usually installed where the fluorescent ballast was located. External drivers act the same way as internal drivers; they accept AC power, convert it to DC which is supplied to the LEDs in the tube.

In the case where you have a native DC system (such as solar systems) you are best to look for externally driven LED tubes and forgo the installation of the driver. You will have to make sure the DC power that is supplied to the fixture is compatible with the DC power requirement of the tubes.

Q33. What is single ended power and double ended power mean in terms of fluorescent tubes?

In single ended powered tubes, you power only one end. This type of installation is referred to as unshunted.

Q34. What is this new series “SWITCH-DIM”?

Switch-Dim is a master innovation series by Remen Led Lites which changes a LED light source from a bulb to a multi-light bulb. A product in this AC series can change lumen output i.e. the amount of brightness it emits with the click of a switch. This comes in a retrofit range and does not require any additional fittings and is good to use with your exiting fittings only.

This lamp is suitable for users who require different amount of light during the day. With every step-down of lumen (amount of brightness emitted by a light source) the wattage consumption also decreases ensuring maximum value over lifetime (ROI).Thus, now you can electricity consumption according to your need.

Currently, the wattages available are 12w-6w-1.5 in one bulb offering lumen output of 1200, 600, 150 and another bulb with wattage 8w-4w-1w with lumen output of 800-400-100.

Q35 . What is Miami Heat?

Miami heat is associated with driver of the bulb/ lamp. Lamps which emit too sharp and bright light have a driver as a component. Heat is generated by an exothermic reaction is an increase in energy of particles causing them to move/vibrate more rapidly, in some materials this can cause electricity to flow more easily, the mechanism of heat evaporation system to optimize the whole process without affecting the life of product is called Miami Heat.

Q36. What is WALS technology?

WALS stands for Wide-Angle Light Scattering which means that the angle of light is wide. Currently we are offering 240 degree WALS in our products.

Q37. What does WVP stand for?

WVP means Wide Voltage Protection. Remen Led Lites products provide wide voltage protection.

Q38. What is Surge Protection?

Surge Protection is a mechanism in an appliance or product to protect electrical devices from voltage spikes. A surge protector attempts to limit the voltage supplied to an electric device by either blocking or shorting to ground any unwanted voltages above a safe threshold. This mechanism is present in Remen Led Lites products.

Q39. According to your warranty policy, will you replace warranty bulbs or not?

According to our warranty policy, we will replace AC bulb within a period of 2years and DC bulb within 1year, the bulb should not be tampered/damaged or used other than purpose specified. Products received for replacement after this date will not be eligible for replacement. For any after-sale purposes, the customer needs to contact dealer.
