— ENGINEERING CANDOR · LAB VS. FIELD

Where the spec-sheet number and the field number diverge.

L70 is calculated against TM-21 lab data at 35°C ambient. Real-world commercial installs run cooler (open-troffer ambient typically 28–32°C) which extends practical service life by 15–20% — but warehouse high-bay applications and recessed downlights can run 5–10°C hotter, reducing it. The published L70 number is the conservative TM-21 calculation, not the optimistic best-case.

Inrush current at install can spike higher than the typical 30A peak when 20+ Workhorse T8s share a single 20A circuit and energize together — circuit re-balancing or staggered control may be needed. We document this in the install guide because the spec sheet alone won't catch it.

BALLAST COMPATIBILITY · 200+ MODELS

Tested across 21 ballast manufacturers. Application-driven.

Per the current tubulⒶRCH T8 Ballast Compatibility List, T8 has been tested against 60+ ballast models from Advance · Arcata · Espen · Fulham · Fusion · GE · Greenhill · Halco · Howard · Huafeng · Keystone · Osram · Pacific · PowerMaster · Plusrite · Premium · Robertson · Standard · Sunpark · TCP · Universal.

Important: compatible ballasts are application-driven. The T8 ballast compatibility list does not transfer to T5HE / T5HO / PL / PLL / U6 — each form factor has its own compatibility list.
