anyone got experience with these bulbs? are they any good?

also whats better, full spectrum or 5000-6500k. i got this expensive 40 dollar 15 watt bulb that is suppose to be used for reptiles to supply UV rays that help the reptiles digest their food and some other stuff. just wondering if is it just me or does this seem to work wonders. i had the light for 2 days and my plants a pearling.

I have a 33watt Grow Light over my 10gallon and so far the plants love it. I do not have proper CO2 in so I dont see the plants pearling, but there is enough to see some bubbles stream from the cuts in the plants The one I got was from Canadian Tire and was 20 dollars. There is an "envirolite t5" there as well which makes up for the lack of lumens in the light.

The pinkish light is a result of spikes in the red and blue parts of the spectrum, which is more useful for plants, vs regular bulbs that are more yellow, which makes them to appear brighter to your and my eye. So generally speaking, they are good. But also you need sufficient light to enter the tank, which means sufficient wattage with a good reflector.

Different things you have read somewhere... full spectrum means it is somewhat close to sunlight, but see above, not necessarily the best for plants. The Kelvin number is the color temperature of the bulb, 5000 to 6500 is pleasing to the eye. If lower everything gets greenish or yellowish.
