All LEDs Are Not Created Equal

By Soriana Stern 

Meet the Juno WarmDim, the LED that dims like an incandescent. Pretty cool—or should I say, warm—huh?

LEDs and Dimming
LEDs typically give off blue or white light, even while dimmed. The WarmDim technology, though, warms as it dims. Many LEDs maintain the same color temperature even as it dims. The appearance of the room stays the same; the light stays the same bluish color. But, with the WarmDim lighting technology, the light turns yellow as it is dimmed.

Below, you’ll find a chart comparing several different lights, and the benefits of choosing WarmDim for your retrofits.

LEDs Over CFLs
Although CFL light bulbs are a popular replacement for the outlawed incandescent light bulbs, CFLs aren’t really meant to work with dimmers. Here’s why:

CFLs generate light through gas. Dimmers work by lowering the voltage in the bulb, giving off less heat, thus lessening brightness. When you cut the voltage to a CFL, the CFLs tend to go out instead of dimming since there isn’t enough voltage to keep the gas ignited.

Just picture a gas stove. Imagine how sensitive it is to the knob to ignite it. When you turn the stove lower, it is difficult to keep the gas ignited—that’s how CFLs work.

Also, CFLs tend to take at least 10-15 seconds to reach full brightness. Some CFLs can take up to three minutes to reach full brightness. It is counterintuitive, and a waste, to use CFLs for dimming, when they don’t even turn on right away in the first place.

Why Dimmers?
Dimmers allow you to control how much light illuminates your room, thus saving energy, and money. Dimmers are most desirable for any room. Reducing the light by 25% yields at least 20% in energy savings. Even though 25% sounds like a lot, it really isn’t. The human eye usually cannot notice a 15-20% reduction in light, so even though less energy is being expended, the change in light output is unnoticeable, as if nothing is changed.

From a design perspective, interior designers actually recommend dimmers because they allow you to “set the mood,” if you will, of your space, creating ambience lighting.
