ColorStars Group Launches the Dimmable R4-MR16-WHT Series MR16 LED Lamps

The 6W R4-MR16-WHT Series of retrofit LED lamps with a GU5.3 bi-pin base represent a milestone for the ColorStars' Group. The R4-MR16-WHT Series features a new heatsink that allows for the highest lumen output yet of any retrofit MR16 LED lamp manufactured by the ColorStars' Group. They are the first lamps to offer a dimmable function with linear AC transformers and some compatible electronic transformers.

Four chips are used in the 6-watt lamps. They provide a lumen output that varies depending on the lens and beam angle, reaching 350 lumens ±10% for the R4-MR16-WHT-D-45.

Four beam angles are available in either daylight white ( 5500k ±200k) or warm-white (2700k ±200k or 3000k ±200k): 30°, 45°, 50° and 55°.

The R4-MR16-WHT series are dimmable with linear AC transformers, some compatible electronic transformers and standard TRIAC dimmers.

The power supply voltage of the R4-MR16-WHT series is 12~18Vac and 12~24Vdc. The power supply current is <500mA. Power consumption is 6 watts. Operating life is projected as 70% lumen maintenance after 35,000 hours. The lamp dimensions are: length – 38mm and diameter – 49.5mm.

Specific models, their beam angles and lumen output are as follows:
• R4-MR16-WHT-W-L-55 (lens) (3000k ±200k; 55° and 235 lumens ±10%)
• R4-MR16-WHT-W-50 (3000k ±200k; 50° and 245 lumens ±10%)
• R4-MR16-WHT-D-L-55 (lens) (5500k ±200k; 55° and 245 lumens ±10%)
• R4-MR16-WHT-D-50 (5500k ±200k; 50° and 260 lumens ±10%)
• R4-MR16-WHT-W-30 (2700k ±200k; 30° and 320 lumens ±10%)
• R4-MR16-WHT-W-45 (2700k ±200k; 45° and 300 lumens ±10%)
• R4-MR16-WHT-D-30 (5500k ±200k; 30° and 350 lumens ±10%)
• R4-MR16-WHT-D-45 (5500k ±200k; 45° and 330 lumens ±10%)

The ColorStars Group is headquartered in Irvine, California, U.S.A. with manufacturing facilities in Taiwan.

Dear Sir,
We have LED lights with UL, CE and RoHs on spot lamp, light bulb, down light and high bay light.
JIESEN LED LIGHTING is a China-based company selling high quality LED lighting products produced by our select partners who are professional lighting manufacturers at country.
We are committed to providing quality, sustainable products that are a direct replacement for incandescent, halogen and CFL bulbs and fixtures. LED lights are solid state, non-toxic, contain zero mercury and are environmentally friendly, so LEDs are clearly a far better choice to cut energy costs and to be safe to the environment.
Should you have any problems, concerns or issue, please feel free to contact us or email us.
Thank you.
Best Regards.
