I agree- Sunlight makes quality stuff. Don't go for the removeable louvers, though, if you're sure that you're going to air-cool the hood. It's a pain to make them really air-tight, which can allow for smell leaks in yer lighting exhaust. Also, they're by definition offset- you'll get better efficiancy if airflow is laminar over the bulb, with the built in vent flanges.

Fer Sunlight stuff, I really like the EconoCool- CoolSun if ya got the scratch.

I'll second the rec on the digi ballast- more lumens=more mojo.

Cool tubes are a drag to keep clean- dust builds up inside, foliar sprays outside. Not my favorite distribution pattern, either, unless you're gonna run a bunch of them in parallel.

rhizome Reviewed by rhizome on . Looking to Buy a 1000 watt hortilux w/coolable refelctor what is the best bang for your buck when buying a 100watt light system with the ability to hook up ventilation right to the reflective hood? I would wanna build a cool tube like I saw in the FAQ section, but im not too good of an electrician and cant quite figure what exactly the steps are. What is everyone's opinion?:rasta: Rating: 5
