Reptiles need UVB to survive. The REPTIDLDB 22-Inch 26W fixture delivers that necessity with adjustable output levels from 10.0 to 20.0. That range covers everything from forest-dwelling geckos to desert basking species like bearded dragons. The 26-watt power ensures consistent coverage across the full 22-inch length of the enclosure.

UVB does three critical things: it triggers appetite, enables Vitamin D3 synthesis, and drives calcium absorption for bone health. Without adequate UVB, reptiles develop metabolic bone disease. This fixture also emits full-spectrum UVA, which supports natural behavior and activity patterns. The dimensions (22 x 2.4 x 1 inches) fit standard terrarium hoods without awkward overhang.

One limitation worth noting: the package measures 28 inches long, so check your shipping space if you live in a tight apartment. The build is straightforward plastic housing with no smart controls or timers. You will need to pair this with a compatible ballast or timer system for automated day cycles. For the price, it provides reliable, adjustable UVB output that meets the basic physiological needs of most UVB-dependent reptiles.
