Has a good inexpensive brand with both 10,000k day and blue in NO
bulbs. It's GE brand. Aquarays saltwater blue 10,000k 48" is 11.99 and the Aquarays fresh/saltwater 9325k day bulb is 48" 10.59. I have ordered these several times in the past and have had great luck with them shipping well and working when they arrive.
