Usage Tips:R7S LED 118MMR7S LED bulb 118mm 20W dimmable, warm white light diffusion angle, low heat ceramic lamp holder, explosion-proof connection structure, COB LED chip Low power consumptionR7S 118mm warm white LED bulb, perfect replacement for R7S J78 80W-100W halogen lamp. Reduce power consumption by 85%. Low maintenance costs reduce problems associated with frequent lamp replacements [Dimmer Description] R7S LED 118mm supports dimming, but is only compatible with with drives based on the SCR principle (silicon controlled thyristor). NOTICED : If the dimmer is not compatible, it will flash when dimming Contains no lead, mercury, UV or infrared radiation. R7S 118MM LED provides a stable light source, soft natural light without glare, greatly relieving visual fatigue Note: The data are all manual measurements, please allow an error of 1 - 3cm, due to the difference in light and display, there will be a certain color difference, depending on the physical object received Delivery quantity: (according to the main image)
