And I'm a little leery of the "6850 lumens"... very, very few CFLs exceed 80 lumens per watt. That's over 100...that's HPS efficiency.

Make it easier on yourself. You can go to Wal-Mart and get one of the 10" Clamp lights for $10, a Y-Adaptor for $1.50, and a 2 pack of Daylight (6500k) grow bulbs for $7.00. That's less than $20 for a good reflector light that puts out about 3500-4000 lumens. It's already got a plug. It's got a clamp, if you want to use that. You can switch out to warm white bulbs to flower if you want...a 4-pack of 23 watters from Wal-Mart is $7. Less cost, more versatility, easier to use. Just my .02
you can get this light at Home Depot for $42 and is very easy to vire up and hang(less than 20mins total). I have 2 of these lights and they are great, the plants love em
