Dimmable LED Down Light Particular: Features include: 1. High luminous efficiency Import high bright semiconductor chip independence device packaging High-power LED as light source, luminous efficiency is more than 100Lm/W, much higher than incandescent bulb 15Lm/W, halogen 20Lm/W, energy saving lamp 50Lm/W 2. Long life time Can work 50000hours with the decay of emitter lower than 15%. 3. High quality With CRI 90 real presentation for true color, which can meet requirement for Museum, Exhibition Hall, stage setting etc. 4. High energy saving Compared with incandescent and halogen, LED will save 85% energy and 50% than energy saving lamp. 5. Green and clean Cold light source design, non-thermal radiation, pairs of eyes and skin without any harm. No mercury and other pollution elements, environmental protection. 6. Universal standard Standard size of diameter rate of cutting hole 2'', 2.5'', 3'', 4'', 6'', 8'' can replace the traditional down light directly, unnecessary to cut new hole for the fitting.
