RV LIGHTING PWM Eco-LED Warm White LED G4 Bulb, with 36 SMD 3014 & Back (90&deg; Angle) Connector(GG4-PWM-WW36) 36 SMD 3014 LEDs in WARM WHITE (3000K-3500K) Input voltage 10-14V DC, output lumen of 205-215 LM, total watts of 1.3 W & consumption of 0.115 A; uses constant current mode that gives a constant brightness, no matter the voltage variation. LED replacement for 12V DC halogen bulbs parts # JC10W and/or G4, and can be used to replace standard G4 LED bulbs in case of interference on radio or television. Dimmable! Uses the Pulse-Width Modulation technology (PWM) in order to allow the use our popular Wireless Wall Switch (WS-01 or WS-01DC), which procures flicker-free 7-step dimming in 12V lighting systems. Designed to last &gt;50,000 hoursan overvoltage protection preserves efficiency throughout its lifetime.
