Carpenter posted his review on 3-3W 9W White High Power LED Light Lamp Spot Bulb E27 October 27, 2013

I bought 10 of these in green. I use them in the evenings in addition to my normal lighting to extend my daylight hours, to help me avoid seasonal depression brought on by short winter days. The green of the Topledlight LEDs, wavelengths 520-530 nm, is effective for circadian entrainment and easier on the eyes than the blue.

They are bright, inexpensive for the amount of light they give, and have good build quality. I would have given them 5 stars except that one of the ten lights did not work. I’ve bought various lights from Topledlight since 2011, that was the only problem I’ve ever had with their products.
