SATCO Lighting S11927 24W T8 LED, Single pin Base, 4000K, 50,000 Avg Rated Hours, 3200 Lumens, Type B, 6ft Double Ended Bypass

It's a ballast bypass lamp, so the existing fluorescent ballast has to come out. Power is wired straight to the sockets, and this one is double ended: line to one end, neutral to the other. It runs on anything from 120V to 277V at 50/60Hz, drawing 0.200 to 0.087A depending on where in that range you land.

Both, within limits. The S11927 is an enclosed rated lamp, so it can go in a sealed or gasketed wraparound without voiding its rating, and it carries a damp location rating. Damp is not wet, so direct water exposure or an unprotected outdoor mounting is out of scope. Burning position is universal, so it can be mounted vertical, horizontal, or base up.

No on DLC. This lamp is not DLC listed, so it won't satisfy a rebate program or a specification that requires a DLC qualified product. It is FCC compliant and Title 24 compliant, which covers California energy code projects. If the job hinges on a DLC listing, you need a different lamp.

No. The S11927 is non-dimmable, and it is not three-way or CCT selectable either. It's a fixed 4000K neutral white output at 3200 lumens. If a space needs dimming control, this lamp isn't the one to spec.

3200 lumens at 24 watts, with an 80 CRI and a 210 degree beam spread so the output wraps around the tube rather than firing in one direction. Satco rates it as a 100W incandescent equivalent. Rated life is 50,000 average hours, which is the number that usually justifies the relamp labor in a warehouse or corridor where ladder time costs more than the lamp.

Type B means the lamp has its driver on board and runs on line voltage with the ballast removed, which is what the S11927 does as a double ended bypass lamp. Type A keeps the existing fluorescent ballast and just drops in, so it's faster but you inherit the ballast as a future failure point and the ongoing ballast losses. Type B takes an electrician and a rewire of the sockets once, then there's no ballast left to fail. For a property manager relamping a run of 6 ft strips that are already due for ballast replacement, Type B is the one that ends the maintenance cycle.

Only if those are 4000K too. The S11927 is fixed at 4000K neutral white with an 80 CRI and no selectable color option, so it will read noticeably cooler next to 3000K lamps and warmer next to 5000K. When you're standardizing a facility, keep the whole run at one color temperature; mixing tubes in the same ceiling grid shows up immediately.

Glass, both the base material and the lens, with a frosted finish that diffuses the diodes so you don't see hot spots through the tube. Glass is fine for general commercial ceilings but it is not the right choice for a gym, a food prep area, or anywhere a shatter-resistant coated or plastic-bodied lamp is required by facility policy.
