DIY HOB lighting

[lectraplayer]

Finished prototyping the 175 watt model. Shown on my 29g tank with a 4000K bulb. Reflector come of a pole light that fell. It works quite well.

I don't know why posting pictures has to be so hard.

Update: After using this configuration for the last 6 months and growing a jungle, I'm back at it again, adding a 13 watt observation only lamp and a reflector plate or two to direct light that originally escaped horizontaily due to the existing reflector I used down into the tank. Pictures to come later...
