Product Overview
The Satco S12372 is a 5.5W LED MR16 lamp with a glass body and polycarbonate lens, designed to deliver light quality and performance similar to a traditional halogen MR16 while using a fraction of the energy. It produces 500 lumens at 3000K with a CRI of 90+ for accurate, true-to-life color rendering, and a 36° flood beam for broad, even coverage.
This lamp is phase-cut dimmable down to 20% and is rated for damp locations and enclosed fixtures. It runs on standard 120V line voltage via a GU10 twist-lock base — no separate low-voltage transformer is required, unlike 12V GU5.3 MR16 lamps in the same family. It is cULus Listed and California Title 20 compliant.
Compatible Applications
- Downlighting
- Cabinet lighting
- Accent lighting
