Satco Lighting S8603 – Frequently Asked Questions

1) Will the Satco S8603 MR11 LED work in a 120V fixture?
No. The S8603 is a 12 volt lamp, so it needs a low voltage system with a transformer feeding the socket. Drop it into a line voltage 120V holder and it will fail immediately. If your track or recessed heads run at line voltage, you need a 120V lamp instead.
2) What base does the Satco S8603 MR11 LED use, and will it fit my existing MR11 sockets?
It uses a GU4 bi-pin base, which is the standard two-pin base on MR11 low voltage lamps. If you are pulling out a halogen MR11 with two small pins on 12V, this drops straight into the same socket.
3) How much light does a 3W MR11 LED put out compared to the halogen it replaces?
The S8603 draws 3 watts and delivers 210 lumens. That is in the range of a 20 watt halogen MR11, so you get similar output at roughly a seventh of the load, which matters when you are counting lamps against the capacity of a low voltage transformer.
4) Is a 25 degree beam angle too narrow for general lighting?
Yes, for ambient fill it is. The S8603 is a 25 degree narrow spot, meant for accent work: artwork, display cases, retail merchandise, signage, landscape uplighting. For washing a whole room you want a wider flood beam. Spacing heads on tight centers is how you use a 25 degree lamp for anything approaching general coverage.
5) What color light does the Satco S8603 give off, and will it match my other bulbs?
3000K, a warm white. It sits between the 2700K of incandescent and the neutral 3500K to 4000K range. If the rest of your fixtures are 2700K it will read slightly cooler side by side, so for a hotel corridor or a retail run standardize the whole line on one color temperature.
6) How long does the S8603 MR11 LED last before relamping?
Rated at 25,000 average hours. For a display running 12 hours a day that is roughly five and a half years of service, which is the argument for swapping halogen MR11s in hard to reach cove and case fixtures where the labor to relamp costs more than the lamp.
7) What part number do I order for the Satco 3W MR11 LED?
Satco S8603. One version only, a white housing, so there are no finish or beam options to specify when ordering.
