Satco Lighting S18451 – Frequently Asked Questions
1) Can the Satco S18451 U-bend LED be installed in an existing fixture without rewiring?
Yes. The S18451 is a Type A/B lamp, so it will run on an existing compatible fluorescent ballast (Type A) or be wired direct to line voltage after the ballast is removed (Type B). That means you can drop it in now and bypass later when the ballast fails. Line voltage range is 120V-277V at 50/60Hz.
2) Will the Satco S18451 fit my 2x2 troffer?
It is a 22.5 inch long T8 U-bend with a medium bi-pin base, which is the standard lamp for a 2x2 recessed troffer or wraparound that currently takes FB32T8 U-bend fluorescents. Check the leg spacing of your existing lamp against the fixture sockets, since U-bends vary by leg spacing rather than length.
3) For ballast bypass wiring, is the Satco S18451 single-ended or double-ended?
Either. In Type B bypass mode the lamp accepts single-ended or double-ended wiring, so it works with non-shunted sockets on one end or line and neutral split across both ends. Current draw is .12A in bypass and .15A when run on an electronic ballast.
4) Does this Satco U-bend LED qualify for utility rebates or California energy code?
The S18451 is DLC approved, which is what most utility rebate programs require for linear LED replacements, and it is listed as Title 24 compliant. It is also FCC compliant.
5) Can I use this U-bend LED in an enclosed lens fixture or a damp area like a covered parking garage?
Yes on both counts. The S18451 is an enclosed rated lamp, so a gasketed or fully lensed troffer is fine, and it carries a damp location rating. It is not rated for wet locations. Burning position is universal, so orientation in the fixture does not matter.
6) How much light does a 13W Satco U-bend LED give compared to the 32W fluorescent it replaces?
The S18451 puts out 1800 lumens at 13 watts, with an 80 CRI and a 160 degree beam spread for even wash across a troffer lens. Satco rates it as a 50W incandescent equivalent. Rated life is 50,000 hours.
7) Will the 3500K color on this Satco lamp match the other bulbs in my building?
The S18451 is a fixed 3500K neutral white and is not CCT selectable, so it will match other 3500K lamps only. If your facility is standardized on 4000K or 5000K, order that color code instead rather than mixing, since the difference is visible side by side in a corridor.
8) Can the Satco S18451 be dimmed or used on a three-way circuit?
No. It is not a three-way lamp, and Satco specifies it for operation either on a compatible fluorescent ballast or direct line voltage at 120V-277V. Treat it as a full-output lamp on a standard on/off switch or occupancy sensor circuit.
9) Is this U-bend LED glass or plastic?
All plastic. The lens is polystyrene with a frost finish, the housing is white, and the base is plastic as well, so there is no glass to break on a shake-out or a ladder drop. Each lamp weighs 0.53 lb.
