Full Spectrum Lamps

Arcadia Reptile D3 and D3+ T8 lamps have been specifically designed with animal health in mind. We are proud to have the world’s highest output T8 lamps in 6% and 12% UVB.

Safe levels of UV-B for a year

All of our UVB percentages are measured as part of the total output of light from the lamp and after the all important first 100 hours of output. You can be rest assured that by using Arcadia Reptile D3 and D3+ lamps that you are providing the very best in T8 technology. The Arcadia Reptile D3 and D3+ UVB lamps are effective to for one whole year and will keep your animal in tip top condition.

Replicates typical daylight

Arcadia Reptile T8 D3 and D3+ lamps have a high UV-A output (30%), providing all the elements which are so vital to the welfare of the reptiles. As full spectrum lamps, they help simulate sunlight. This provides high colour rendering for enhanced viewing of your reptiles and their environment. The colour temperature of 6,500K replicates typical daylight conditions.
