ADL Supply Expert Application & Replacement Guide
Philips describes the MASTER TL5 High Output range as optimized for lighting efficiency at 35°C ambient temperature and as allowing more compact luminaires for lighting system minimization. It is specified for offices, industry, schools and retail environments where T5 HO fixtures are already installed.
The 54W HO lamp must run on gear rated for T5 High Output 54W lamps. Do not mix HE and HO lamps and ballasts; use a ballast rated for the exact lamp wattage listed.

Ballast & Fixture Compatibility
Use an electronic ballast rated for 54W T5 High Output lamps and confirm the rating on the ballast label or fixture nameplate before installing. ADL Supply can help match a ballast to your fixture if you send us the label.
Before You Order – Verify
- Confirm the fixture and ballast are rated for a 54W T5 HO lamp; T5 HE and T5 HO lamps are not interchangeable.
- This is the MASTER TL5 HO at 6500K (865). ADL also lists a Silhouette F54T5/865/HO/ALTO with different published ratings (82 CRI); confirm which family your fixture requires.
- Specifications follow the Philips Lighting Catalogue (NZ edition); check the current Philips datasheet for new project specifications.
- Confirm 6500K matches the lamps already installed before partial re-lamping.
