Gan chargre
Gallium nitride, or GaN, is a material that's starting to be used for semiconductors in chargers.The main thing about GaN when it comes to chargers is that it produces less heat.Ultimately, this means your devices will charge faster with a GaN charger than with a silicon one. In summation, GaN chargers are more power efficient, significantly smaller, and capable of charging your devices much faster than a silicon-based charger.

The test object is a six-inch LED PAR36 lamp (or AR111). The test results show that the overall performance of such LED products lags behind other LED directional lights, such as PAR30 (BR30). The measured object has a maximum lumen value of only 588 and a power range of 31 lm/W to 58 lm/W. Although it is higher than a halogen lamp, it is much lower than other types of LED lamps. Among the six lamps tested, the color properties of the two lamps and the conventional halogen lamps were different, and all the test objects were not as narrow as the PAR36 halogen lamps in terms of beam angle.
The number of samples selected for this round of testing is nearly six. This is because the LED PAR36 lamp is limited to a very subdivided professional market. It is rare in the United States, so it is difficult to find such products on the market. Many large factories do not have this. Class products.
Overall, CALiPER's LED lighting products are increasingly approaching or surpassing their traditional lighting competitors. The LED downlight of the first round of CALiPER testing was only 19 lm/W, and by the ninth round it was 61 lm/W.
In the fourteen round test, the performance of 11 6-inch LED downlights is much higher than that of halogen or incandescent lamps: 10 out of 11 products meet the ENERGY STAR-related color temperature and color rendering index standards, and the efficacy is not lower than CFL. Downlight luminaire system. Starting in 2012, each summary report is focused on a single product type or application. 
DOE: Most LED PAR36 can't effectively replace the same type of traditional halogen lamp
On August 15, the US Department of Energy (DOE) released the results of the 17th round of the CALiPER project. Tests have shown that at least a majority of LED PAR36 lamps do not effectively replace the same type of conventional halogen lamps, and color and light intensity distribution are the main aspects of failure.
