Simple division returns 69.56 lumens per watt for the CFL and 70 lumens per watt for the HPS. I don't see the advantage of the extra expense for a HPS lamp and cool tube. |
Higher wattage HPS are more efficient. They really aren't very expensive, but it is relative.
For me HPS gives:
- Less lights - you wont need a dozen to 1/2 dozen bulbs in your cab
- better penetration than CFLs. A 250W hps can penetrate a foot.
- More lumens per watt than CFL(which is a shitty way to measure light. Lumens are for our eyes)
- Better control over heat - cooltubes will make a cool cab.
- faster flowering time than CFLs
- yealds are larger than CFLs
Now, I do use CFLs to side light in my cab and it works great.
You might want to look at either the stanlety blower at walmart (30-40USD) or the blue blower at home depot / lowes (50-70USD) for a cheap blower that you can simply modify. I have a blue blower that has 3 speeds 100, 200, 300 CFM that I got for 70USD. I took lots of metal tape and attached it to my 6" duct to cool my lights and vent out the cab.
Good Luck!
