SATCO Lighting S11953 5 Foot, 22W, Linear LED T8, Type B Ballast Bypass, G13 Bi-Pin Base, 80 CRI, 4000K

No. The S11953 is a Type B ballast bypass lamp, so the fixture has to be rewired for line voltage direct to the sockets and the existing fluorescent ballast removed or disconnected. Leaving the ballast in circuit is not an option with this lamp. If you want a lamp that runs on the existing ballast you need a Type A plug-and-play tube instead. Once rewired, the lamp accepts 120V through 277V at 50/60Hz, so it works on either common commercial branch circuit.

No. The S11953 is non-dimmable and it is not CCT selectable or three-way, so it runs at one fixed output and one fixed 4000K color. Putting it on a dimmer or an occupancy sensor with dimming control is not a valid application. If your space needs dimming, specify a dimmable linear LED instead.

The S11953 puts out 2800 lumens at 22 watts with a 160 degree beam spread, which is a wide distribution suited to general overhead strip and troffer work. Color is 4000K neutral white with a CRI of 83, so it reads cooler and whiter than a 3000K lamp without going into daylight blue. Current draw is 0.183 to 0.079 amps depending on supply voltage, which matters when you are counting lamps on a circuit.

It is rated for indoor use in damp locations, so a covered walkway, a garage, or a stairwell where humidity gets high is within rating. It is not a wet location lamp, so direct exposure to rain, spray, or washdown is out. Mounting orientation is unrestricted, the burning position is universal, so vertical strips and horizontal troffers both work.

Title 24 compliant, and FCC compliant. It is not DLC listed, which is the hurdle most utility prescriptive rebate programs use, so do not budget a DLC-based rebate on this lamp. If a rebate is part of your project funding, pick a DLC listed linear LED.

Order Satco S11953. It is the 5 foot, 22W linear LED T8 in 4000K with a frosted glass lens and G13 bi-pin base. There is no color-temperature or wattage variation under that number, the frost finish is the only configuration, so the number alone is enough to get the right lamp on the job.

Both the lens and the base material are glass, with a frosted lens finish and a white housing. Glass handles better on relamping than some coated plastics but it will break, so for a gym, a kitchen line, or anywhere with impact or food-safety exposure, a shatterproof coated or all-plastic tube is the better call.

Average rated life on the S11953 is 50,000 hours. On a 12 hour a day operating schedule that is roughly 11 years of service, which is why most property managers rewire once for ballast bypass and stop replacing ballasts entirely.
