SATCO Lighting S11956 30W T8 LED Type B Ballast Bypass, G13 Bi-Pin Base, 80 CRI, 5000K

No. The S11956 is a Type B ballast bypass lamp, so the fluorescent ballast has to be removed and line voltage wired directly to the sockets. Dropping it into a ballasted fixture will not work. If you want a no-rewire swap, you need a Type A (ballast-compatible) tube instead. Plan on a qualified electrician for the socket rewire.

The lamp uses a medium bi-pin (G13) base, the same pin spacing as a standard fluorescent T8, so it seats in existing tombstones. What changes with a ballast bypass lamp is the wiring behind those sockets, not the socket pattern itself.

No. The S11956 is non-dimmable, so it has to be on a straight on/off switch or relay. Wiring it to a dimmer can cause flicker or shorten lamp life. For dimming-controlled areas, specify a dimmable tube or a dimmable LED fixture.

Not through DLC. The lamp is not DLC listed, and most commercial utility prescriptive rebates for linear LED require a DLC qualified product. It is Title 24 compliant, which matters for California projects, and it is FCC compliant for EMI. If the rebate program drives your spec, look for a DLC listed tube.

It runs on any line voltage from 120V through 277V at 50/60Hz, so the same lamp covers residential 120V and commercial 277V lighting branch circuits. Current draw is 0.250 to 0.108A depending on where in that voltage range you land.

The tube puts out 4000 lumens at 30 watts, which Satco rates as a 125W incandescent equivalent. At 5000K it reads as crisp daylight white, the usual pick for shops, warehouses, parking garages and back-of-house areas rather than offices or lobbies where 3500K or 4000K is more common. Color temperature is fixed, not selectable, so every lamp in the building will match.

It carries a damp location rating and is an indoor lamp. That covers enclosed areas with humidity or condensation, such as locker rooms, covered walkways and unconditioned storage. It is not for wet locations or direct exposure to weather. Burning position is universal, so you can mount it horizontally, vertically, or in a strip at any angle.

Glass, with a frosted glass lens and a white housing. The frost diffuses the diodes so you do not see hot spots through an open strip fixture, and the 160 degree beam spread gives near-full forward distribution, which suits wraps, troffers and strips. Glass construction means normal care in high-impact areas, like gyms or docks, where a coated or plastic tube is a better call.

Rated average life is 50,000 hours. On a 12 hour daily schedule that is roughly 11 years of service, which is why the ballast removal labor on a Type B retrofit pays back over a fleet of fixtures. With 83 CRI the color rendering is typical general-purpose commercial quality.
