Came across some Daylights

I friend of mine is giving me a 4 bulb 48" fixture ...and he also has a couple of 'Daylights' which I understand are about $7-$8 bucks. Is this the same as a cool light, or better? ...and should I combine several types of bulbs for optimum results?

RE: Came across some Daylights

"Daylight" bulbs covers a wide variety of bulbs, but all will have a colour temperature between 5000K and 6500K, bluer than a standard cool white which is 4000K or 4100K. They may be a fairly standard triphosphor bulb with a lot of blue or they may have a more advanced "full spectrum" formulation to provide much better colour rendition. The full spectrum bulbs tend to be quite a bit more expensive but not necessarily any better for plants. Treat them like a cool white, results may be somewhat better, but don't spend big money on a daylight bulb unless you check the spectrum to be sure it will be better for your plants.
