Question about 96 watt CFL

Dubstepsoldier

So I am doing all the math for my CFL setup, trying to find the most lumens at the best wattage and price. I found the most cost effective to be 96watt CFL's which produce 8600 lumen at 5000k and under, and 8100 lumen at 6700k. For roughly 5 sq. feet of grow space I was thinking about going with two 96 watt and two 28 watt (each 2100 lumen) giving me a grand total of 20,900 lm for 248 watts.
I have noticed that most people doing CFL have 6 to 10 lights between 30-45 watts each. Is there an advantage to having more lights at a lower wattage than having only a couple at a high wattage? Where I live a 36w CFL cost $20 while the 96w cost $34. The added bonus with the 96 watt is that when I change the spectrum for flowering I will only have to buy 1 or 2 bulbs instead of 6 or 8 new ones all over again.
The only thing that I can think of is that with more bulbs you can spread the light better. However, the 96 watt lights are 2 pronged long, skinny guys, so If they sit horizontal the light should spread out fine.
Will I have heat issue with higher watt lights?

And lastly, is there and advantage to the coil lights versus the 2 (or 4) pronged lights? I hope all of this is coherent! Thank you!!

the only advantage is as you said, being able to spread the light simply because there is more to move around where you want them. there is always more heat with more wattage, no matter the bulb.the prong cfl's might actually have the advantage because they have features from both the coil model and the t5 model fluorescents. (just my opinion)

hope that helps but wait for more info from others

scott, where in the world did you find a 27000k cfl bulb or any other bulb of the sort. 6500-6700k daylight is the brightest used for veg. and 2700k for flower. if there are 27000k, i would love too see them.

I think when stoned folks type, shit happens and he hit one too many 0's I rekon

Cannibal Sativa

well even if it is a mistype, he's still giving wrong info. 6700k is for veg. and 2700k for flower.

Must be some good dope cause he and I have discussed this and he does know which is for which. He just must of smoked too much or been tired. He will fix this when he comes on. don't want people to get confused.

Peace

CS is soo correct...thanks for catching my mistake...I must remember...Never smoke and type

of course the correct info is 6500k for veg and 2700k for flower

you can hang me for getting sloppy but I am going to chalk it up to the quality of my Mazar

seriously CS is correct...there is no excuse for giving incorrect info to someone that is trying to get help on this site...I've gotten better and everyone deserves better...so I'll be much more careful but you can be sure that as a human I will make mistakes...it's great that there are peeps out there checking...I would do the same if I came across it...one person can never be as helpful as a diverse community when it comes to this stuff.

I'm not trying to start debate, but adding all the lumens to get a grand total for the area is somewhat inaccurate. Reasons why i believe this is because CFLs have little penetration over a far distance therefore losing it's lumen output...accurate? IMO it's more accurate to say that there is xxx amount of lumens in this given area--another reason why it is spread throughout the plant.
I know this maybe no big thing, but for new people using cfls they may not understand that having 10cfls on the canopy is different from having an hps/mh lighting on the canopy.
Hope this makes sense--i'm sill a lil baked from pre-work session.

it does make sense....HID lighting is well Higher Intensity and so tends to penetrate more deeply and create bigger buds...so comparing cfl and hid lumens can be like comparing apples and oranges as you correctly point out. lumenousity can be only accuratly measured with a light meter at the spot you want the light regaurdless of what the manufacturer prints on the bulb...but the guidlines for cfl lumens on the canopy have worked very well and are very good way of calculating if you have enough light...I always figure if I go into a thread thinking the exact same thing when I go out of it, then I haven't learned anything..so I don't think of as a debate (most ardent debaters can win arguments, but that doesn't mean they are correct) but rather dialogue and perhaps at most deliberation
