Satco Lighting S18452 – Frequently Asked Questions
1) Can the Satco S18452 U-bend LED be installed in an existing fluorescent troffer without rewiring?
Yes. The S18452 is a Type A/B lamp, so it will run on an existing compatible fluorescent ballast (Type A) with no rewiring at all, or you can bypass the ballast and wire line voltage direct to the sockets (Type B). It supports both single-ended and double-ended wiring on the bypass side, so it works with either socket arrangement you find in the fixture. On ballast it draws .15A; bypassed it draws .12A.
2) What size U-bend fluorescent tube does the Satco S18452 LED replace?
It is a 22.5 inch overall T8 U-bend with a medium bi-pin base, which is the standard 2-lamp or 3-lamp U-tube format used in 2x2 troffers. If your existing U-tube has the medium bi-pin pins and the fixture is a 2x2, this drops into the same sockets.
3) Can I use the Satco S18452 in a closed wraparound fixture or a damp location like a parking garage?
It is an enclosed rated lamp, so sealed and lensed fixtures are fine. Location rating is damp, which covers covered exterior soffits, garages and similar; it is not rated for wet locations with direct water exposure. Burning position is universal, so it can be mounted in any orientation.
4) Is 1900 lumens at 13W enough to replace the U-tube I'm pulling out of a 2x2 troffer?
The S18452 puts out 1900 lumens on 13 watts at 4000K neutral white, with an 80 CRI and a 160 degree beam spread so the light fills a frosted lens troffer evenly rather than striping. Satco rates it as a 50W incandescent equivalent. In a two- or three-lamp 2x2 you are stacking 3800 to 5700 lumens, which covers typical office and corridor levels.
5) Will this U-bend LED work on 277 volt building power?
Yes, it is rated 120V through 277V at 50/60Hz, so it covers both 120V and 277V commercial circuits when wired as a Type B ballast bypass lamp.
6) Is this U-bend lamp dimmable or color selectable?
No on both counts. The S18452 is fixed at 4000K with no CCT selection switch, and it is not a three-way lamp. If you need tunable color across a facility, this is not the lamp; standardize on 4000K or pick a selectable-CCT tube instead.
7) Is this U-bend LED glass or plastic? I need shatter resistance for a food service area.
All plastic construction: polystyrene frosted lens, plastic body and plastic base, no glass tube. It weighs 0.53 lb, well under a glass U-tube, so it puts less load on old sockets.
8) How long do these Satco U-bend LEDs last before relamping a building full of 2x2 troffers?
Rated life is 50,000 hours. At 12 hours a day that is roughly 11 years of service, which is why most MRO buyers pair the retrofit with a ballast bypass: once the ballast is out of the circuit there is no second failure point to come back for.
