LED vs Fluorescent & Incandescent
Green Building Initiatives, in conjunction with Eco Lighting Solutions™, supplies only the highest quality LED lighting available. Eco Lighting Solutions™ LED lighting products are “light years ahead of the competition”.
All Eco Lighting Solutions™ LED products are commercial quality, containing only high-output LED chips from the top chip manufacturers. High output, combined with the latest advancements in driver technology means more light output, reduced energy consumption and longer life.
When we look at LED bulb efficiency there are two things that factor in to how many lumens the bulb produces per watt of energy consumed:
1) The efficiency of the driver
An 8 Watt Conventional 400 Lumen LED warm white bulb probably contains an 80% efficiency Driver. That 80% efficiency driver will generate 1.6 watts of wasted heat energy which must then be dissipated through the heat sink. By comparison, manufacturing that very same bulb with a 92% efficiency driver, means we can create the same amount of light with only 7 watts of electricity consumption. As you can imagine that extra watt of savings will save you even more energy. The bulb will run cooler and you can expect it to maintain its light output much longer than other less efficient bulbs.
2) The efficiency of the chip
Let’s take the bulb that we just upgraded the driver on and swap out the LED chips to high output LED chips. We can now either produce the same lumens with less chips (lowering the cost), or we can increase the light output from the bulb.
Bulb Design Factors
Now that we have decided on the best driver and chips available for the bulb, let’s take a look at its design. Bulb design is a critical factor in how well it distributes light, and how well it cools itself.
1) How well does it distribute the light?
Light distribution often the most overlooked factor in choosing LED bulbs. A well designed bulb projects light over as wide an area as possible. The wider the beam angle the better. Look for a bulb that has a lens design with a round sweeping lens that sweeps backwards as much as possible towards the base (the 6.5 Watt bulb below is a good example).
Omnidirectional bulbs are also a great example because the bulbs direct the light outward and away from the bulb instead of straight out the top of the bulb. They usually are well worth the additional cost. Lamps, outdoor lights, and general purpose lighting are the best applications for an omnidirectional.
2) Cooling technology
A well designed heat LED bulb cooling system allows a bulb to cool itself better and the cooler an LED bulb operates the longer it will last. All Eco-Lighting Solutions Bulbs have well designed heat management systems to give you the long life you expect.
Our new 6.5 watt 450 Lumen Super Light led bulb shown to the left contains a 92% efficiency driver, high output chips, a sweeping lens design, and a highly efficient cooling system.
All of our commercial quality LED products use this philosophy so they generate less heat, and operate at cooler temperatures, greatly extending their lifetime. With an Eco Lighting Solutions™ LED product you can expect better color accuracy control, lower energy consumption, and longer life.
