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.

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

At first, I really liked these bulbs for helping keep my circadian rhythm in line. However, after using the bulbs for about a month, two out of four bulbs started to flicker and became unusable. Now, a few months after that, the other two bulbs have given out. That’s a defect rate of 100%.
The company contacted me when the first two bulbs turned bad and promised to send me new ones. They failed to do so. Now, I have four bulbs that are junk. This was a total waste of money, which is a shame because they were nice bulbs when the worked.
Update: The company promised to send me new bulbs, but they never did. Now, three of the four bulbs are flickering and are unusable. That amounts to a failure rate of 75%. This was a total waste of money.

Can you still turn them on/off with your regular light switch? If using regular light switch will it auto be on last used setting? Thanks.
If you set the lights to a certain color and turn off the lights from the switch then when you turn the switch back on they will resume the last thing it was set to the package comes with two remotes so if it??s for one room you can leave the remote by the door and one elsewhere in the room and always keep the switch on??

What is the difference between this product and another 10W 4 pack that you offer for $29.99?
It equivalent to 75W bulb,so far this is the highest brightness color changing light bulb in our shop.
The equivalent to 60W color changing light bulb of ours, some customer left review said “bright”, and some other said” not enough bright”, so we designed equivelant 75W color changing light bulb to meet more custo??
