Not sure what type of bulb I have.

[Josh Q]

I bought a 7 gallon tank about two years ago for my first tank and it has one 14 watt flourecent light that makes the tank kind of a purpleish color. I'm wanting to put a few real plants in but not sure if it's a full spectrum light or not and "14 watt" is all it says on the bulb. Does this sound like a light that will be able to help the plants? Thanks.

If it is extremely purplish, like a black light, then it is actinic, but if it has just a purplish hue, then it is probably a 50/50 bulb wich means that it is 50% actinic and 50% of some sort of daylight spectrum. Plants will do ok with this type of light.

Make sure to buy a new one though. Flourescents lose efficiency after about six months of use.
