Satco Lighting S8538 – Frequently Asked Questions

1) Does the Satco S8538 LED PL lamp need the existing ballast removed?
Yes. The S8538 is a Type B ballast bypass lamp, so it runs on line voltage direct to the socket. The existing CFL ballast has to be removed or bypassed and the socket rewired before the lamp goes in. Leave the ballast in the circuit and the lamp won't operate correctly.
2) Will a G24d 2-pin socket accept the Satco S8538?
The S8538 uses a G24d 2-pin base, so it seats in a standard 2-pin PL socket. It will not fit a 4-pin G24q socket, which is a different pin arrangement. If your existing lamp is 4-pin, this is not the right replacement.
3) Can the Satco S8538 PL lamp be mounted horizontally in a fixture?
It's specified for vertical orientation. In downlights and vertically socketed PL cans it performs as rated; for horizontal sockets in wall sconces or under-cabinet housings, look for a PL lamp rated horizontal instead.
4) What light output and color does the 9W Satco S8538 give compared to the CFL it replaces?
1000 lumens at 4000K, a neutral white that reads clean rather than warm or blue. At 9 watts it covers the output range typical PL CFLs in this socket produced, and the 120 degree beam angle spreads light broadly rather than spotting.
5) Is 4000K the right color temperature for office and corridor relamping?
4000K is the neutral white commonly specified for offices, corridors, garages and back-of-house. If the rest of the building is on 3000K warm white or 5000K daylight, the S8538 will read visibly different in the same sightline, so match the existing temperature when you're relamping only part of a space.
6) How long does the Satco S8538 last before relamping?
Rated at 50,000 average hours. On a 12-hour daily schedule that's roughly 11 years of service, which is why facilities crews use the ballast bypass conversion to take PL fixtures off the CFL and ballast replacement cycle entirely.
7) What is the Satco part number and finish for the 9W 4000K PL 2-pin LED?
Satco S8538, supplied in a frost finish. That MPN covers the 9W, 4000K, 1000 lumen, G24d 2-pin, Type B ballast bypass lamp.
