DOE announced the seventh round of CALiPER project test results

U.S. Department of energy (DOE) commercially viable LED product evaluation and reporting (CALiPER, Commercially LED Product Evaluation and Reporting) project seventh round of testing has ended.

A series of products of the seventh round of testing includes three fields: outdoor lighting, lamp and lamp replacement.

The key points covered in the test report are "stable improvement in light efficiency, color quality, power factor, and accurate reporting of SSL products by manufacturers. Unfortunately, the market still has a variety of products show large differences in performance, the test results show that the optical efficiency of outdoor SSL lamp is 19-71lm/W, and the light efficiency of SSL downlight is 9-48lm/W. "

Accuracy of manufacturer's product specification

In the seventh round of the CALiPER project, we can see more accurate and complete product performance reports compared to the previous rounds. However, the report found that 50% of the products tested were found to be inaccurate or inadequate.

Test details

The seventh round of tests, which began in September 2008 and ended in January 2009, tested a total of 29 products, showing a wide variety of product types and technologies.

One of the series of tests consists of 8 types of street lights: 5 SSL lamps, 1 'typical' high pressure sodium lamps, and two lamps for fluorescent lamps. In order to outdoor lighting, CALiPER project also tested 3 kinds of guardrail lamp: semiconductor lighting, compact fluorescent lamp and metal halide lamp.

The report said, "the test object is another series of 9 kinds of lamp (8 SSL, 1 kinds of compact fluorescent lamps (CFL)), including a series may be applicable to downlight lamps, including lamps, tunnel lights, veneered embedded downlight, and a 2 x 2 inches flat lamp etc.. Alternative lamps include 9 different SSL products, which can be replaced by the product includes: MR16s, some larger indicator (PAR20, PAR30 and PAR38) and A- lights. "

conclusion

Guardrail lamp: take two different products using different light source side by side comparison, there can be convincing results. The fluorescent lamp, metal halide lamp (MH) and SSL in the light of the direct comparison of the fence, you can find the lamps used in SSL than in CFL and MH light effect is better. "

Street lamp: "a series of tests for outdoor street lights show the performance characteristics of a variety of lamps, such as the effectiveness of lamps, light output, light distribution and color characteristics. "

"By the early downlight CALiPER downlight test, coupled with obviously to the test results, 9 different downlight, they have the same light output, but the efficiency of light light efficiency of SSL products more than incandescent lamp and halogen lamp products, and most SSL products to light effect directly with CFL tube lamp match. "

Instead of a light: "although many SSL replacement lamps are still facing the performance description is not accurate or not full color quality problems, but some tested with low power replacement lamps, incandescent and halogen lamps compared to remain competitive. "
