GU10 LED Bulbs, 6-12 Pack 4W MR16 Track Lights with 300 Lumens and Four Color Temperature Options
These GU10 LED bulbs refresh compatible track lights and recessed fixtures with focused, efficient accent lighting. Each 4W MR16 lamp produces 300 lumens as a 35W halogen replacement, while a 40-degree beam highlights counters, displays and seating areas without spreading light across the entire room.
Choose six- or twelve-bulb packs in listed 2700K warm white, 3000K warm white, 4000K neutral white or 5000K daylight. The standard GU10 twist-lock base installs in matching 100–120V fixtures, and the non-dimmable lamps are rated beyond 15,000 hours. Use a regular on-off circuit because pairing these bulbs with a dimmer may cause flicker.
