I have a pretty extended experience with lizards husbandry and always struggle to find the right bulb i.e. providing the right spectrum and reliability. Mega Ray is the best bulb I tried, period. I even made a test in a large cage to have a Mega Ray bulb and a competitor product (same power) and most of the lizards cam below the Mega Ray. Speaking enough. Not least they last about twice competitors' products.
PS: I am a private person. Genuine buyer and tester. I have no financial interest at all with Mega Ray.
This bulb has cured my baby of a deficiency she was suffering. The bulb that came with her adoption was not sufficient for her needs and she was developing metabolic bone disease even though she had proper diet. Since she is now getting the proper lighting the disease has reversed and she has improved 98 percent! She loves to bask and seems so much happier and healthier. This bulb is HIGHLY RECOMENDED!
This light puts off a balanced amount of UVA and UVB at a constant level that my reptiles need along with heat so I can do it all with one bulb I really recommend this product for anyone who has reptiles that require UVB and UVA
