Homnebila’s fixture emphasizes balanced UVB/UVA for vitamin D3 synthesis and calcium absorption, aiming to reduce Metabolic Bone Disease risk. It features a reflective coating that purportedly increases UVB output and a T5 HO ballast for stable operation. Best for a range of reptiles in 22″ or similar terrariums where higher UVB intensity helps drive growth and health. Limitation: higher output may require closer monitoring of enclosure temperature.
REPTI ZOO T5 HO UVB Lighting Combo Kit
This kit features a high-output T5 lamp with a low-profile design and a polished curved reflector for enhanced UVB delivery. The included T5 HO electronic ballast supports rapid start and steady performance, with plastic end covers for safety.

The package emphasizes space-saving design and an energy-efficient ballast for rapid lamp startup. Best for smaller reptiles or vivariums where 5.0 UVB is sufficient to supplement natural light. Limitation: lower UVB intensity compared to 10.0 setups, so choose if your species requires moderate exposure.
Hygger Zoo T5 UVB Reptile Light Fixture HO
Hygger Zoo offers a 22″ fixture with 10% UVB output and a curved reflector to maximize UV delivery. The aluminum hood aids heat dissipation, supporting longer bulb life and stable operation.

Buying Guide
What to look for when choosing a T5 HO UVB fixture:
- UVB intensity: Many reptiles benefit from 10.0 UVB; some species do fine with 5.0. Match to your animal’s needs and basking distance.
- Reflector design: A highly polished, curved reflector increases UVB/output efficiency and coverage.
- Ballast type: A stable T5 HO ballast minimizes flicker and provides reliable startup. Look for integrated ballasts to simplify setup.
- Heat management: Aluminum or alloy hoods aid heat dissipation to prevent enclosure overheating.
- Bulb replaceability: Replace UVB bulbs per manufacturer guidance to maintain proper output and animal health.
- Terrarium suitability: Confirm hood length and bulb wattage fit your enclosure dimensions (22″, 12″ or 14″ models are common).
