I got one of these. Works good, and survived being rained on when my tank bottom cracked. The clamp socket failed and the light is still going strong in a new socket.
I'd like to see the Kessil H80 vs one of these cheapo lights. I can justify a $100 to replace one of these a lot easier than a $300 light.

Essentially the Amazon-style plant bulbs (of which there are dozens) out perform a regular daylight bulb by about 50%. The Kessil out performs the Amazon bulbs by almost 100% which is insane. Of course the Kessil is great, but the Amazon bulbs are incredible value. I'm referring to the mass of the growth of chaeto -- They all were capable of reducing nitrates and phosphates to 0.
