Most LED MR16 performance less than 50W halogen lamp?

The United States Energy Board (DOE) recently released the latest CALiPER test results, found that only a small number of LED Lighting Facts tag with 50W (12V) halogen lamp performance equal to MR16.

The report pointed out that only a few light angle and center beam strength (center beam intensity) LED MR16 light energy star (Energy Star) the lowest standard center beam, the standard MR16 50W halogen lamp, light emitting angle of 40 degrees as a benchmark.

Although the past three years to get a LED Lighting Facts label light up slightly, the proportion of the recording lamp class fell from the previous three years to 4% in. The new LED MR16 average optical output (light efficiency) in the past two years, almost no change. Despite the steady growth of LED MR16 lumen output as well as power over the past few quarters, the results do not have much effect on the light efficiency, light efficiency change little.

Overall recorded in the LED Lighting Facts under the MR16 lamp, the color quality is better than other types of lamps, color rendering index (CRI) of more than 90 of the higher proportion of MR16.

Like other types of lamps, LED Lighting Facts included in the LED MR16 lamp performance varies, consumers should assess their own product performance.
