ADL Supply Expert Application & Replacement Guide
The Sylvania FP35/841/ECO is primarily specified by electrical contractors and facility maintenance teams for replacement in 5-foot T5 HO fluorescent fixture installations — commercial office troffers, retail ceiling strips, and utility lighting systems built on the 5-foot T5 HO platform. The 57.61-inch overall length is the 5-foot class T5 format — it is not compatible with standard 4-foot T8 or 4-foot T5 fixtures. Confirm the fixture accepts 57.61-inch T5 lamps before ordering. This lamp is a T5 HO (High Output) lamp operating at 35W — T5 HE (High Efficiency) lamps in the 5-foot class operate at 28W and use different ballast operating parameters. Confirm the ballast is explicitly rated for T5 HO at 35W — T5 HE ballasts are not compatible. The G5 miniature bi-pin base is the standard interface for all T5 linear fluorescent lamps but T5 HE and T5 HO ballasts differ; the correct ballast class must be matched.
Before You Order
| Verify Before Ordering 5-Foot T5 HO — Not Compatible with 4-Foot T5 or T8 Fixtures | T5 HO Ballast Required — Not T5 HE | State Shipping Restrictions Apply This is a 5-foot (57.61-inch) T5 HO lamp — it will not fit 4-foot T5 or any T8 fixture. Confirm the fixture accepts 5-foot T5 HO lamps. Confirm the ballast is rated for T5 HO at 35W — T5 HE ballasts are not compatible. Confirm 4100K cool white matches your installation. |

Operation, Safety & Mounting Compliance
T5 HO vs T5 HE, 5-Foot Format & G5 Ballast Compatibility
T5 HO (High Output) and T5 HE (High Efficiency) lamps share the same G5 miniature bi-pin base and are physically similar in diameter but operate at different currents and require different ballasts. T5 HO lamps at 5-foot length operate at 35W; T5 HE lamps at 5-foot length operate at 28W. Installing a T5 HO lamp on a T5 HE ballast (or vice versa) will result in incorrect lamp current, reduced lamp life, and potential ballast overload. Always confirm the ballast specification sheet explicitly lists 35W T5 HO as a compatible lamp load before installation.
Mercury Content & Disposal
This lamp contains mercury and must be recycled through a certified lamp recycling program in compliance with applicable federal, state, and local regulations — do not discard in standard municipal solid waste. This product cannot be shipped to CA, CO, HI, ME, MN, OR, RI, or VT.
