CFL vs LED?

It depends on what ones you are comparing. If you compare £100 worth of each, the CFLs will win hands down. If you have 100 watts used (not rated) of each it's the LED that will come out on top 

 

1) yes, that one would cover around 1-2 square feet of area and yield around 1 oz without any major cock ups. Colour spectrum most suited to flowering but can be used for vegging also.
 
2) same as above but around half the watts so would cover around half the area and yield half also. Colour spectrum most suited to vegging but  again can be used for both.
 
3) nothing wrong with that tent but with 8 square foot of area you would need so many of those bulbs you linked to you would be better off spending the money on an HPS light

 

or a good LED

 

 
An LED that could cover 8 square feet is going to be out of his budget I would think. I mean, he's looking at 20 buck bulbs 

 

My fault

 

 
Nah man you have a valid point, and you are right. It's just I would think an LED would not be an option for him. I could easily be wrong about that though, I was just presuming

 

I received my 180w LED today and I love it, the penetration is way better than CFL's, Less heat than my 35w CFL, built in fans, hangers etc... I would rather have it better than like 10 CFL's dangling around haha

 

TYVM for that link, I been looking for 105 watt 2700ks!!!

 

Those are going to put my CFL grow to over 1300 watts!!!!! I didnt think 2700k 105watt E26 bulbs existed yet lol

 

 
The bulbs look solid but here is the only thing. That tent is 2x4x5 my room is 6 ft/wide x 4ft/tall x 3ft/deep. Using bulbs pretty similar too what you posted it takes 12 to fill it. You could get away with way less I'm sure but 12 seems to be the magic number in my room for best lighting. That could raise other issues for you.
 
Do you want to buy 10-12 bulbs at 20 bucks apiece?
Will you be able to vent that much heat? and trust me cfls can get hot as fuck if you arnt careful and roast the shit out of plants.
Would it be easier to go small Hps or Led? instead of rigging up 8-12 bulbs?
 
The choice is up too you all your preference and style bro!

Though they are not CFL, FL tech is not as efficient at emitting the intensity required by our plants. LED clearly better at this. AND, without the heat that fluorescents radiate.
 
Hope this helps,

CFL because LED sucks look at the results lol
I'm doing a DYI LED light setup next.
 

 

I'd be a supporter of LED. If you cannot afford LED lighting though, CFL is definitely a viable alternative for an ounce or 3 every once and awhile.
