Trimlight offers three bulb options. The Classic Bulb has 1 LED — the long-standing reliable workhorse. The 3L Bulb has 3 LEDs and is significantly brighter, matching our Commercial Bulb’s output. For most Middle Tennessee residential installs, we typically spec the 3L for larger estate-style homes (Brentwood Annandale/Governors Club/Witherspoon, Franklin Westhaven Highlands, Forest Hills) where the brighter punch reads better at distance, and the Classic for tighter rooflines and smaller-lot suburban builds.
