Pros: A warm, bright LED based bulb that only uses 9.5 watts!
Cons: Warm tone has a very slight green tint to it... bulb failed in under 5 months.
This is basically a Par38 (Fits R40 as well) style bulb that uses 165 LEDs inside instead of an incandescent, halogen, or CFL source. It actually looks "pretty" when off as the LEDs are just below the lense giving it a cut crystal look... which is getting off-track, but some people might think that's cool.
Anyway - it is a 100-watt-equivalent bulb that only uses 9.5 watts. Awsome! It is truely bright and lights up an area well, although the lumen output is not quite a 100w equivelant - probably closer to a 60w incandescent. It is a warm tone (Kelvin rating is not listed). My wife and I decided the best way to describe the light is a warm white with a very slight green tint... It is not green, but a very slight hint of it. (emphasize "very slight", tiny hint)
Liked the "instant on" aspect of the bulb, as CFLs tend to start out dim.
It is an indoor/outdoor bulb - we were using ours on the porch - the warm light matched the solar LED landscape lights we have in that area. Definately a big step in LEDs becoming the bulb of choice in the near future.
Price was closer to US$47.00 when shipping is included - hopefully prices will come down a bit in the future as well...
Unfortunately a "ring" of LEDs within the bulb failed after about 4.5 months of use. EarthLED took it back (I paid to ship it back), and they were very willing to send a replacement - once they verified the failure - or a credit towards a different bulb they offer. I am actually going to get another CL-5 bulb as I have a couple of those and like them very much. They are paying the shipping to send the new bulb to me - I only need pay the difference in bulb costs. Even though the EX-38 failed, the company's customer service was very professional, helpful, and quickly communicated any status on the exchange.
