LOW wattage CFL's VS HIGH wattage CFL's

HookdOnChronics said:

EVERY grower should know this if they're already growing! That's a no brainer! HID is ALWAYS better! ALWAYS! That's not waht this thread was started for, because obviously HID lights are far superior to CFL's, everybody should know that! This is just discussing the difference in HIGH and LOW wattage CFL's.

Thankyou for the link though! Appreciated!



Here's a CFL grow, using ONLY 26w CFL's..... I've got more plants and pictures if you'd like to see. lol

Is that yellow lighter a mini bix or are they really that huge?!

Wow man! They look extremely dense for cfl's! Great job! More bud porn please!

On my next grow, I am thinking about hanging a few small banks of T-5s on the 3 walls of my grow room w/ my cfls. This way the plants are completely covered w/lights

No sir! If it was a mini bic I would say so. I'm not trying to pull a quick one on anyone here. That's is just a regular sized bic lighter. And those are big boy buds! lol, It's all about learning HOW to use the CFL's, along with training AND pruning. You learn how a certain straing grows, learn how much you can train/prune it without causing it too much stress, and you can most definitely do things like this with PURE CFL lighting!

My pleasure! And thankyou! Sommore CFL buds for ya here. Enjoy!


I may have gone a little overboard..... But I just threw up a tone of random bud/plant pix. lol, Hope it's not too many. Again, 100% CFL lighting for ALL these plants!

HookdOnChronics, you surely can grow nice lookin bud. I just harvested all of my plants, Sunday 7-11-10. I harvested 5 colas 2 weeks ago because they were showing alot of amber. Out of those 5 colas, I got alittle over an ounce and a half. Haven't figure out how to read my digital scale LOL
Anyway heres a few photos I'd thought you would like I'll upate ya w/photos of my harvest in a week or so, stay kool

I hate to be the one to rain on everyone's parade but recently my thoughts were crushed when I read that lumens DO NOT compound. What I mean is if you've got 23W bulbs that emit 1500 lumens, if you have ten of those bulbs that does NOT equal 15,000 lumens. It equals 1500 lumens, spread out. It's something I'm still coming to terms with, but with that understanding, the only real way to get those high lumens is to use the 150W - 300W bulbs, then use a good reflector to spread it out evenly or use multiple large wattage CFLs to get the desired coverage. Just a little food for thought.

Alright guys so I made this a while ago when a buddie of mine started asking me "Why not use the big, 150W CFL's instead of all these smaller ones" So I did some research! lol, Here's what I found out, just tryin to spread the love to any other CFLers out there!

Hookd’s info on CFL’s.

Just a little FYI here. But CFL's start to loose their lumen per watt output after about the 30W cfl's. So if it's possible for you, I'd go with an abundance of smaller CFL's, (mathamatically the 26W bulbs are the most efficient lumen/watt wise) rather than 1 HUGE CFL. Because the ONE MASSIVE CFL doesn't put out as many lumens as if you we're to use the same amount of watts, just with more, smaller light's. Does what I'm saying make sense?



Here, this may be better:

I looked at the 150W CFL's, and the one that puts out the MOST lumest/watt that I could find is the "150 Watt CFL Light Bulb - 650 W Equal – Soft White 2700K - 9,200 lumens"
So the best lumen/watt for a large, 150W CFL that I found was 9,200lumens/150watts which calculates to about 61.333 lumens per individual watt.

Now I looked at the kind of light's I use which are the "26 Watt CFL Light Bulb - 105 W Equal - Soft White 2700K - 1800 lumens"
So the best lumen/watt for the smaller, 26W CFL that I found was 1800lumens/26watts which calculates to about 69.231 lumens per individual watt.




Ok so let me break this down for you, straight G style! Hahaha:


A single, 150W CFL, puts out 9200 lumens total. 61.333 lumens per watt.
Now let's see here, 150W/26W=5.796. So it would take about 5.796 of these 26w cfl's to have the same amount of watts being used as the 150w. So let's round that down (just to make a point) to 5 of the 26watt CFL's, that would be a total of 130watts, and you would be putting out 9000 lumens. So for 20 less watts, you would have only 200 less lumens. (Don't forget I rounded down to 5 instead of 5.796 just to make my point.)
If you were to round up instead of down, from 5.796 to 6 which is what logic would tell us to do. That would give you 156watts (Only 6 watts more than the 150w CFL) and 10800 lumens (which is 1600 MORE lumens {almost an entire 26W CFL worth} that the 150W CFL)

So 1600 MORE lumens for only 6 more watts.

Again, just sharing some info. This is what I do instead of using the HUGE CFL's. It's also a LOT cheaper to replace these smaller bulbs for whenever the time comes. Because it's said that CFL's start to lose intensity after about 3 grows. Just some food for thought.

Don't FUCK with me and my CFL's! lol
Hope this helps with your decision. And if not, at least I was able to spread the knowledge. PEACE

Alright I KNEW I read something that states this is incorrect. But I wasn't going to say anything without being able to provide some sort of factual evidence. Anyways I was just doin some reading and I came back across it. It's in one of the 'stickys' I'll post exactly what is says. Then I'll toss up a link. At the bottom of the first post in the link, you can clearly see how the ambient lights is DOUBLED, when he turns on an extra light of the exact same wattage ect... LOOK: https://www.rollitup.org/indoor-growing/83128-lumens-lux-adding-all-up.html

And here's what was said in that 'sticky':
"If you put two lights the same distance from a point, and each light provides N photons per unit area at the point, with two lights you will have 2N photons per unit area at the point. Because intensity is a measure of the number of photons per unit area, the light is twice as intense, whatever unit you choose to use. Twice the lumens, twice the lux, twice the footcandles. "

i use the largest cfls haha i have two 105 watt two 150 watt and one 200 watt, there awsome and all, but they deffinitly get hotter than the smaller ones and cant cover the same amount of area. im currently flowering uner two 105s and a 150, but i was just at the store yesterday to get some 45's cause my plants need more light in hard to reach places, i rarely find a use for the 200 watt its almost bigg enough were i could put a cola "in" it but sure it would burn it

you can see my plants in my sig haven't put the 45s in yet

Well that settles that. I'm officially still confused In any event, we know you can grow serious buds with CFLs, and even with low-wattage. I guess it's all in how you use the light you've got.
