Satco Lighting S8643 – Frequently Asked Questions
1) Is a 40 degree beam MR16 a spot or a flood?
Forty degrees is a flood. The S8643 spreads light wide enough to wash a wall, cover a work surface, or light a seating area from a track head, rather than punching a tight pool on a single object. If you are accenting artwork or a display piece and want a defined circle of light, a narrower beam MR16 (typically 15 to 25 degrees) is the better pick.
2) What does 4000K look like, and will it match the other bulbs in my building?
4000K is neutral white, the clean commercial color you see in offices, corridors, retail and back of house. It reads cooler and crisper than the 2700K to 3000K warm white used in hospitality and residential, and warmer than 5000K daylight. If the rest of the fixtures on the floor are 3000K, this lamp will stand out next to them, so keep the color temperature consistent across the run.
3) What is the manufacturer part number for the 8W 4000K GU5.3 MR16 from Satco?
Satco part number S8643. That is the number to quote for the 8W, 4000K, 40 degree beam, GU5.3 base, 12V AC/DC MR16. Satco numbers a separate S code for each color temperature and beam angle in the family, so quoting S8643 pins down exactly this combination rather than the adjacent lamp.
