Protection circuit. No false promise.

The best thing is that size and for the price currently on the market. It is quite okay that the device switches back after some time to prevent overheating. With a push of a button you can switch to the phenomenally high output of 960 lm again. In normal life, but the fact is important that you have a very bright lamp, the electronically controlled protects itself from harm! Those who prefer different likes, please. Always better than a defective bulb. But of course there are also people who send therefore be right back!

From me full justified 5 star!
