SATCO Lighting S18453 13W T8 U-Bend LED, 50000 Hours, Medium bi-pin Base, 2000 Lumens, 5000K, Type A/B, Ballast Dependant or Ballast Bypass

Yes. The S18453 is a Type A/B lamp, so it will run on an existing compatible fluorescent ballast (Type A) or you can bypass the ballast and wire line voltage direct to the sockets (Type B). Type A is the drop-in route: pull the old U-bend, put this one in, done. Type B takes the ballast out of the circuit so you stop replacing it, and this lamp supports both single-ended and double-ended wiring for that conversion.

The S18453 puts out 2000 lumens at 13 watts, 5000K, with an 80 CRI and a 160 degree beam spread, so a two-lamp 2x2 troffer lands around 4000 lumens. That covers typical office, corridor and retail ambient light at a fraction of the draw. 5000K reads as a crisp daylight white, noticeably cooler than the 3500K or 4100K fluorescents in a lot of older buildings, so expect a color shift if you are only doing part of a floor.

The S18453 is an enclosed rated lamp, so a gasketed or fully lensed troffer is fine. It carries a damp location rating, which covers covered exterior soffits, garages and similar damp spots but not wet locations with direct water exposure. Burning position is universal, so it can be mounted horizontal, vertical or any angle.

Yes. The lamp is rated 120V to 277V at 50/60Hz, so it covers both 120V residential and light commercial circuits and 277V commercial branch circuits when wired as a Type B ballast bypass. Current draw is .15A on an electronic ballast and .12A on ballast bypass, which is what you need for counting lamps on a circuit.

The S18453 is DLC approved, which is the qualification most utility rebate programs require for linear LED retrofits, and it is listed as Title 24 compliant for California work. It is also FCC compliant. Keep the DLC listing handy, since rebate paperwork is usually filed by model number.

Not as a dimming lamp. The S18453 is not CCT selectable and is not a three-way lamp, and it is specified as a Type A ballast dependent or Type B bypass lamp rather than a dimmable one. Switched control such as a relay or occupancy sensor that cuts power is fine; for dimmed zones, spec a dimmable LED troffer or a dimmable driver based retrofit kit instead.

Go the Type B route. The amp draw is published for operation on an electronic ballast (.15A) or on ballast bypass (.12A), so for a magnetic ballast fixture the safe path is to bypass and remove the ballast, then feed line voltage straight to the sockets using single-ended or double-ended wiring. That also means a non-shunted or shunted socket check depending on which wiring method you pick.

Body and lens are plastic, with a polystyrene frosted lens and a white housing, so it is shatter resistant compared with a glass fluorescent U-tube, which matters in kitchens, gyms and schools. The frost lens diffuses the diodes so it reads as an even tube rather than visible dots. It weighs 0.5 lb.
