There's a lot of different types of both of those bulbs, but I believe the main difference is the spectrum. I *think* that power-glo is intended for marine aquariums, which would make the frequency too high for most freshwater ones. You'll want a bulb rated between 5,500k-10,000k, 6,700k is best for your average freshwater plant.

Power Glo has a higher color temperature (5400K), Sun Glo (4200K) puts out more actual light (Higher lumens - not sure what it would be at 15 watts, but it looked to be 20% higher than the Power Glo at 40 watts). Go with Life Glo if you have a choice - 6700K and an internal reflector that intensifies the light to over 3x that of Power Glo.

The tint in the light is the color temperature. Very roughly speaking, higher temperatures are better for plants, not so good for algae. (Has to do with available wavelengths)
