With all the problems with the Megaray bulbs, I had to purchase a new bulb. My 100 Watt Megaray only lasted 1-1/2 months, which I'm finding out is common. I've got emails in for the warranty, but as others have found, no response so far. My local stores had either the Zoo Med Power Suns or the Exo Terra Solar Glo bulbs. After reading more negitive info. on the Solar Glos, I opted for the Power Sun 100W. I was curious to read in their instructions that these bulbs need to be mounted vertical rather than on an angle. They claim that if they are mounted on an angle, then they might burn out prematurely. I changed the mount and now have it completely vertical. Are these the new bulbs of choice with Megaray now out of the picture?
