CFL_King, could you take a look at my post in my topic for my current build in progress? You popped in their briefly to talk about some stuff, but I'm trying to figure out some additional information.
Basically, my lumen count is only around 3200 for my build right now. I have decided to add a second socket for a light, but am debating between going with a single secondary 27 watt bulb at 1700 lumens, or two 15 watt bulbs on a Y-connector at about 950 lumens each.
Mind you, this will be for a secondary socket, as the first socket currently has a 42 watt CFL in it and runs at about 80 degrees F average for heat.
So not sure how many more lumens or watts added will affect the heat.

yo, is anyone in the uk? if so im wondering if they have had more luck than me in obtaining decent high wattage cfls. the highest i can find is 23/30 watt but people on here are allways talking of 42watters etc but i just cant find any! ive seen the envirolights but they seem rather expensive.

Sounds a bit out there, but companies will pad their numbers sometimes. who knows, it might really put out that much. only available in 6500k in that wattage though.
Eh, I'd call Bs.
I joined the CFL club recently with 2x 105W CFLs for vegging. Lumen output was like 6700 or something. That's 105 lumens/watt (supposedly those light of america lights), versus 63 lumens/watt. Dunno, 60% extra output seems pretty far fetched.

What's up CFL King?
Anyway, I think your CFL club is great but I had a concern about

We know light is only reflected off of surfaces not volumes, but given certain surface areas the lumens per square foot may not be applicable.
If your cab was 40 inches deep with plants on the bottom and Clfs on the top your Cfls would have a different effect than if they 1 inch from the plant.
We must determine a maximum distance that the bulbs can be from the plant in order for the plant to maintain reasonable leaf/bud production.
With that known you can state that
within a given vertical distance (feet, inches, etc).cfl...KING said:
I hope this helps. Peace..
those numbers are based on the CFL bulbs being 3-6inchs above the canopy.

has any one ever tried these? They are rather big wattage to have in Medium base. I have only ever tried the external ballasted CFL Mogul base like shown above.

took me ages to find some that are available to uk but here you go matey-http://www.bltdirect.co.uk/item617.htm hope that helps
ive bin having the same problem.i have a cab that is around 2 1/2 ft tall containing 2 plants that have just bin put into flower.started off under 2, 20w cfls but just bought and installed a 250w growking cfl so that should do the job. im also gonna put 1 or 2 of the above linked lights in
when i get the funds anyway!
anyone else use these 250w cfls? im a bit worried bout temps. wili i need to cool them?? thanx guys and great work everyone!
felix2: if your ventalation system is that quiet im gonna asume at most its moving 50cfm-80cfm, so unless you have that bulb in a cool tube then temps will be a big problem. i think you should start with a couple 42w CFLs an see how yuor temps are.how big is your space?

alright so im building a single 30+- gallon rub-tub, ive got 2 cfls with a combined output equal to 150w incandescent in a y socket thing, these are daylight bulbs, now my question is should i stick with the daylights or get 1 warm and 1 cold or w/e? ::edit:: also do i need more power? my goals are to grow out some bagseed to find a suitable mother keep here in this tub, and have a perpetual clone/flower tub

6-8,000 lumens per sq ft @ 5-6,500k for veg an 8-10,000 lumens per sq ft @ 2,700-3,000k for flower, thats based on the CFLs being 3-6 inches above your canopy 8 inch max. multiply the lenght x width of the 30 gal rubber maid to find your sq ft. an we go by actual wattage not equivelent an mostly go by lumens then wattage because different wattages get better lumens per watt then others.
