If you are planning to replace your home’s CFL (Compact Fluorescent Lightbulbs) lights with LEDs (Light-Emitting Diode Bulbs), you are making the right decision. The cost of LED is high for now, but over time they are much cheaper than conventional lighting solutions. Before buying the LED lights, there are certain things you should know. Here are the things you should remember while purchasing LED Bulbs for home or office.
1. Consider Lumens, not watts
Wattage is not the indication of brightness; it is the measurement of how much energy the bulb draws. For traditional incandescent bulbs, there is an accepted correlation between the watts drawn and the brightness, but for LEDs, watts aren’t a great predictor of how bright the bulb will be.
Next step is to calculate the bulb’s lumens per Rupee. How many lumens does it produce, and how much does it cost? For example, an LED bulb produce 800 lumens and costs Rs.750, lumens per rupee is 1.06lms/rupee. This number should be as high as possible. It is the easiest way to measure if we are purchasing a value for money product.
2. Choosing the right colour
LED bulbs are capable of displaying a variety of colour range. For home we usually chose something similar to the light of incandescent bulbs light. Warm white and soft white LEDs will produce a slightly yellow hue, close to incandescent. On the other hand, Bulbs labelled bright light will produce a whiter light, closer to daylight and similar to what you see in retail stores.
The colour temperatures are measured in a unit called Kelvin (K). A warm yellow light has a lower colour temperature with a lower Kelvin value (around 2700K), giving a comfortable atmosphere. White light is about 3000K or more. Bright white light is between 3500K to 4100K and While cool blue light offers higher colour temperature with a higher Kelvin value (5000K to 6500K), which is more energising.
CRI or Colour Rendering Index tells you how accurate the colours will appear under the bulb’s light. it should be ranging from 0 to 100, incandescent bulbs are 100. CRI differences fewer than 5 points is insignificant. For interior lights a CRI of 80 is generally recommended.
3. Dimmable LEDs
If you want to control the amount of light, you will have to buy a dimmable LED bulb. Most dimmers installed in our home won’t work with LEDs, because they only control the electricity sent to the bulb. In case of an incandescent bulb, this dimmer will work, the less electricity the incandescent bulb uses, the dimmer the bulb. LEDs are so power efficient and there won’t be much change in limiting the current using a dimmer. So get an LED bulb with dimmable feature, if you want to control the ambient light of your room.
4. Not all LEDs are created equal
There are many cheap brands in the market, who produce LED bulbs with lesser life span. They don’t fulfil their promises or properly adhere to industry standards. SO always go with a trusted manufacturer. The performance of the LED bulb is based on the LED chip used in it. Better the chip, better the bulb. High quality chips last longer and deprecate less over time. Both the level of light and quality of light will be same even after years. However, it costs more for that quality. You don’t have to buy the most expensive LED bulbs from market, just stay away from cheap manufacturers. So beware of cheap LED bulbs or tube lights made using lower quality Chinese LED chips.
5. Lifespan of the bulb
Lifespan is definitely one of the most important factor while purchasing an LED bulb. Most LED bulbs are claimed to last 20,000 to 50,000 hours. Let’s take an LED bulb that has a 50,000 hours of life span as an example. If you use that LED bulb for 8 hours a day, that bulb might last for 17 years! If you use it for 12 hours a day, it could last for 11 years.

What’s new in LED Bulbs
LED bulb is basically an electronic device which mainly focuses on lightning. Now, manufacturers are adding sensors, cameras and speakers into LED bulbs. Means LED bulbs not only provide light, but also security, safety and music.
Now there are LED lights with motion sensors, which will be very much helpful. Also known as an occupancy sensor, it automatically turns on lights when activity is detected and shut them off after activity stops indoors or a short while later outdoors.
Chose a Brand
Philips LED bulbs are the most expensive in the market, because they do not compromise in quality. All Philips LED bulbs above 7 watts are efficient in terms of power factor and CRI. Philips is the No.1 LED brand in India, they provide 15000 hours of LED chip life which is in average quality range.
Syska is the new emerging brand in LED bulbs market. Syska LEDs provide high power factor and CRI.
Havells doesn’t make good quality LED bulbs. Only their Adore 15 watt has 100 lumens per watt, which is very good.
Eveready is the one and only LED bulb maker in India, who is labelling 100 lumens/watt in each of its LED bulbs. But their below 9 watt models have low power factor. Lower power factor means; it will consume more energy.
Wipro doesn’t make a lot of LED bulb models. Wipro has impressive lumens/watt, CRI and power factor, so definitely consider them.
So top bards to consider are Philips, Syska, Everyday and Wipro, because they give good Lumens per watt. Brands like Charlston, Oreva, SYSKA, and Surya gives maximum warranty. LED Bulbs from Moserbear, Charlston has long life LED chip. Brands like Philips, Osram, Eveready, Wipro, SYSKA, Charlston, Surya and Moserbaer have high power factor. Osram, SYSKA and Charlston have high CRI.
