Just as compact fluorescent
light bulbs have all but fully replaced incandescent lights in nearly every
application, LEDs are on their way in. In much the same fashion, LEDs are
plagued by high initial prices that are taking time to come down.

Even
with the high price of LEDs, their advantages are many.Although this article
shows that Cree's led lighting and
Philips LED product sales are not equal it is important to note that Philips LED
salesLED grow light suppliers in China are sky lanterns rolling out models with
better price-performance ratios. One common complain about compact fluorescents
is the ramp-up time to full brightness. Even instant-on CFLs have a ramp-up
time; they start at a relatively low lumen count and then steadily get brighter
until they've reached maximum lumens.

With the instant full intensity of
LEDs, they are great for rooms/applications where cycling is a factor (turning
on and off frequently). Repeated power cycling does not harm or hinder LED light
bulbs. On a similar note, LEDs can also be dimmed as normal, albeit by slightly
different means; a pulse-width modulator or lowering the forward current.



LEDs have a "slow failure", that is their failure is a gradual dimming
with a stop at the end. Incandescent bulbs have a direct failure that can easily
result in bulb explosions if not carefully handled during removal.

LED
size can be misleading considering the tiny size of the bulbs and their
incredible life span, which is estimated at 35,000 to 50000 hours. If you use
the LED light bulbs in the right places (away from extreme heat), they should
attain the aforementioned life spans.

I've seen LED lamps in use to
replace flood lights in a basement. They didn't provide the same amount of light
as I would have wanted, but they must have been an equivalently lower wattage
than the incandescent had been.

I think that with all the advantages of
LED light bulbs, once the prices start coming down we'll see them used a lot
more in homes and business. They're already being used in the streets with LED
traffic lights, although that has raised issues of its own. Nonetheless, I look
forward to using them in my home. Some of my favorite things about CFLs are the
various color temperatures you can get to customize as you see fit.
