Bests & Worsts Reviews from Amazon

I purchased six of these bulb for outside lighting. As I see there are many questions regarding these bulbs I will provide more descriptive answers to many of the questions submitted here. These bulbs internally use eight white LEDs in a ring pattern surrounding four RGB LEDs in a center square pattern. The bulb is well constructed and has dimensions of ; Max Dia. 1.707in /43.36mm Length 4.673in / 118.69mm Using a Kodak 18% gray card I measure the color temperature at 5700K The remote functions well and allows easy control of all the bulb functions . Of the red, green, and blue LEDs of course the green looks the brightest since it is right at the peak color sensitivity of the human eye. Beware though the blue LEDs used in this bulb are actually brighter. The human eye is not as sensitive to blue so it just looks dimmer. You should not view the blue ( or any bright LED) at close range since you eyes will not respond effectively to protect your vision. Also in measuring the light output it was observed the blue LED output forced UV sensitive ink to florescence so there must also be some UV emitted by the blue LEDs. You will see in the tables below extended specifications for this bulb. Probably more than most will need however I feel there is something there for everyone.

I hope they work in cold weather better than the specifications state since my Christmas temperatures can be far below the -20C specification.
