I have 4 BRAND NEW 48" T8 Bulbs for a fresh or saltwater aquarium
Being the idiot that I am, I bought these top of the line bulbs to test on my tank which ones I liked, only to find the I could not return them to Petland, as they do not accept returns on bulbs. So, my loss is your gain. The Bulbs I have for sale are as follows:

1: 48" Power-Glo Bulb- It is 40W and is 18000k. The box says that its ideal for: Freshwater, Saltwater, Coral, Invertebrates, Planted Aquariums- Asking $20
1: 48" Aqua-Glo Bulb- Also a very nice bulb with 40W and 18000k. Ideal for: Freshwater, Planted Aquariums- Asking $15
1: 48" Life-Glo Bulb- This one is more of a white light. Its 40W and 6700k, Ideal for Freshwater, Planted Tanks- Asking $15
1: 48" Flora-Glo Bulb- Best bulb for planted aquariums. Has a high red-blue spectrum for plant growth, can also be used with terrariums- asking $20
