I have had my bearded dragon for about 6 months now, and have been through 6 diffrent megaray bulbs now, and with the current one I just recieved I am having the same eye closing issues. I know they are trying really hard, but at this point I feel it is time to move on to another bulb. I have a 75G aquarium and was thinking about a 2-3 ft reptisun 10.00. Can anyone atest to their quality or pluses and minuses. Any help would be great.
