Buying Guide: T5 Aquarium Light Units and Alternatives
What to consider when choosing a light for your tank:
- Tank type and inhabitants: Reef, freshwater planted, or general aquaria require different spectrum and intensity. T5HO lamps provide bright, broad coverage; LED blends can favor color rendering and energy efficiency.
- Fixture compatibility: Ensure your ballast, hood, and mounting options support T5 tubes or LED modules you choose.
- Spectrum and PAR: Reef tanks often need strong actinic blue and high PAR in midday, while planted tanks require balanced white and spectrum for plant growth.
- Programmability: Timers and dimming features help simulate natural day/night cycles and support coral or plant health.
- Maintenance and retrofit: Some units are easier to upgrade with new tubes or LEDs; others are fixed in design.
