CFL Use

those are ok. over priced... you could get two 42 watters for 9 bucks a piece at home depot. 18$. with that you pay 36$, 55 watts, they dont even list the lumen output, and you pay shipping. if your going to ebay get a 125w envirolite :D shop smart.. unless you rich, then do whatever you wish! personally i'd go to home depot before i took that deal!
 
yeah russ I am going to agree with ouy. you can get alot of lights for $45 at HD or walmart. you can get a 42 watt cfl that is rated for 150 watts for $9. you can fill your grow space with these get more lumen output, i think they give of 2700 apiece, save money and get a better yield.
 
They do list the Lumen output.

Light Output (Lm) 3600

But it is not that great.

I have 2 29 watters from HD that give off 2200 lumen each. So you could push 4400 lumen at 58 watts. And for only $18-20 for both.

can you actually switch to 12/12 using the same cfl's (with a smaller yield of course) I was thinking about doing the same thing but just sticking with these for veg and flower.

sorry i must have missed that

42watt(2700lumen) = about 64 lumen per watt
55 watt(3600lumen) = 65 lumen per watt

they are slightly better. but the price is definitly over the line :D
 
not that it matters but u get 2600 lumens in a 42 watt cfl, which is equal to 150 watt of incandecent light, and yes fuck ebay hd will have what u need

I decided to check on Ebay to see what I could find for lights. I want to use CFLs so do i want something like this?

eBay: Two Daylight 55 W/5000K Compact Fluorescent Light bulbs (item 110080165683 end time Jan-23-07 10:45:46 PST)

meijer sells 45w cfl for $10 a pop, and they have these 50 or 55w bulbs for like 10 or 15 but they have a weird socket. for 20$ they have the "outdoor" reflector box and of those weird socket bulbs.

they also have a wide variety of cool and warm bulbs. ii might go out there today and maybe take pictures of what they have

CFLs are produced in varying shades of white:
  • "Warm white" or "Soft white" (2700 K - 3000 K) provides a light very similar to that of an incandescent bulb, somewhat yellow in appearance;
  • "White", "Bright White", or "Medium White" (3500 K) bulbs produce a yellowish-white light, whiter than an incandescent bulb but still on the warm side;
  • "Cool white" (4100 K) bulbs emit more of a pure white tone; and
  • "Daylight" (5000 K - 6500 K) is slightly bluish-white.
The "K" denotes the correlated color temperature in kelvins. Color temperature is a quantitative measure. The higher the number, the “cooler”, i.e., bluer, the shade. Color names associated with a particular color temperature are not standardized for modern CFLs and other triphosphor lamps like they were for the older style halophosphate fluorescent lamps. Variations and inconsistencies exist among manufacturers. For example, Sylvania's Daylight CFLs have a color temperature of 3500 K, while most other bulbs with a "daylight" label have color temperatures of at least 5000 K. Some vendors fail to include the kelvin value on the package, but this is beginning to improve now that the ENERGY STAR Criteria for CFLs is expected to require such labeling in its 4.0 revision.

btt that is a gimmie, already know all that and some. i can even calculate kelvin from deg^c and ^f. what you are failing to realize is that no individual mentioned the lumen count being 5k. was wondering why he said that?
