I just wanted to let people know about my experience with Mega Ray SB 100 watt self-ballasted Flood lamps. I bought 6 of these and received them in January. Since then, three have burnt out when I first turned them on in the morning. I paid $46.95 a piece for them. After doing some searching on the internet I saw a suggestion from someone saying to make sure you have the fixture plugged into a surg protector so I have now done this with my 3 remaining bulbs We will see how this works. I have decided to take a loss with this purchase because the company requires a 15% restocking fee, plus $10.00 for each bulbs returned. Then you only get a bulb back with the remaining 6 month warranty on it. This would be at least a $72.15 pay out for me to return the bulbs. Then I have the hassle of shipping them and paying postage. I have gone back to Zoo Med products.
