12W GU10 AR111 LED bulb with 4000K natural white light, designed to common 100W halogen or incandescent floodlights. A brightness option using a COB chip for strong illumination with low light attenuation, delivering about 1200 lumens while consuming far less power. Key features and benefits Bright, efficient replacement for 100W halogen/incandescent floodlights: 12W, 1200 lumens, natural white 4000K. light: COB chip for strong illumination and minimal attenuation, resulting in brighter, more durable performance. Dimmable with smooth range: 10%–100% dimming, allowing adjustable brightness to suit different needs. CRI > 80 provides good color rendering close to natural light and helps reduce eye fatigue. Requires an LEDcompatible dimmer. Energy saving and long life: PCceramic construction for better heat dissipation, giving up to 30,000 hours of life (about 10x longer than typical halogen bulbs). Lower power consumption contributes to lower electricity bills and less frequent replacements. Easy to install: standard GU10 base (twist and lock). Installation is straightforward: insert the lamp pin fully, then twist to lock. Lamp size 111 mm x 66 mm (4.37' x 2.60'), weight 200 g. Lightweight, instant full brightness, no flicker, no noise.
