What's the whole concept behind LEDs? By using the correct spectrum of light only, you don't need as much power, right? So you use about 75w of LED power and you "get the same growth rate as a 600w HPS", right? WRONG!

We all know that this is good in theory, but doesn't work in practice. LEDs just don't have enough light intensity or lumen output to make this work. But what if we applied this same idea to CFLs? We will get the benefit of the correct spectrum, but without losing lumens, so its a win/win situation! Getting a mix of red and blue CFLs will work like a "hybrid" of CFLs and LEDs, and we all know hybrids are all the rage these days.

Compact Fluorescent Colored Light Bulbs

They are low wattage's, but CFLs have more efficient Lumen/watt ratios at lower wattage's. Don't believe me? Do the math for yourself. Plus, you can get better coverage to more parts of the plant with more low wattage bulbs than with more high wattage bulbs.

Good thing lumens DO add
Lumens, lux, and adding it all up.



Comments/concerns/insults? Please post. I wanna hear y'alls thoughts...

Interesting theory, but i know leds work well, and with enough you can get the power of a HID with only using LEDs. It just costs a lot more to buy the set-up.

You should start a journal, buy some of these colored CFLs, put them to the test, and stop posting this everywhere =)

i saw these on ebay too, but by the looks of things its not the colour of the light made, its made by the colour of the glass, im not sure but thats what i think, any one!?!?!

i believe the true color is the radiating heat, ie spectrum of light it is in. And that is produced by the filament not the glass. Could be mistaken but let's see what others think.

that ^ sounds right

i just emailed a person on ebay to ask about these and they said:

Hi,

It is the gas in the bulb that is coloured and not the glass. I'm afraid i couldn't tell you the spectrum of the light but I can tell you it's quite a pinkish red as opposed to a bright vibrant red.

Hope this helps

Thanks for that, this helps much. I will do some more research but I think this will work because florescence use a gas to produce the light and if it works like neon lights it is in the right spectrum =)

iv seen these at my local hardware store. The glass is colored. Ive thought about this method. I have 3 CFLs in my PC case and im thinking about switching out one of them to a red or blue CFL.

But yeah, the glass is colored, they also come in orange and yellow. Ill swing by and take a picture of the lights.
