SATCO Lighting S11730 15W 48in T8 LED, 35K/40K/50K CCT Selectable, Ballast Bypass with Battery Backup, G13 Base, 120-277V

The S11730 is a 48 inch T8 LED with integral battery backup, so when line power drops the lamp keeps itself lit off its own battery instead of relying on a separate emergency ballast or a remote inverter. That lets you cover egress lighting inside an existing troffer or strip fixture rather than adding a dedicated emergency fixture. Normal operation is 15 watts on 120-277V.

One part number covers all three. The S11730 is CCT selectable between 3500K, 4000K and 5000K, set on the lamp itself, so a property manager stocking one box can match warm white office areas and cooler 5000K back-of-house without carrying three SKUs. Color rendering is 83 CRI at any setting.

No on vapor tight. Satco states the S11730 is not for use in fully enclosed vapor tight fixtures. It is an indoor lamp rated for damp locations, which covers things like covered walkways, parking structures under cover and humid stairwells, but not direct wet exposure and not a sealed enclosure.

Current draw on the S11730 runs 0.125A at 120V down to 0.054A at 277V. Size your branch circuit off the higher figure when you are on 120V line voltage. That is per lamp, so a two-lamp troffer doubles it, and each fixture on a bypass job is wired direct to line.

Construction is an aluminum base housing in white with a frosted polycarbonate lens, so it is not a glass tube and it will not shatter the way a fluorescent does when it gets knocked in a warehouse or a school corridor. Average rated life is 50,000 hours.

No. The S11730 is not a three-way lamp, and as a ballast bypass emergency tube it is built to run at full output on straight line voltage from 120V to 277V. Put it on a standard switched or unswitched circuit, not on a dimming control.
