Personal Opinion:

I've tried a lot of LED lamps (10 Manufacturer / 8 types of lamps) and am of the opinion that there is no better lamps having such a price. Clear the LED lamps are manufactured in China, as well as some well-known manufacturers such as Osram, GE, and Philips.

The price is determined by the fact that the materials used are cost-effective.

The lamp assembly is similar to that of halogen lamps (glass reflector). From well-known manufacturers such as gennannt already above the lamp consists partly of high-quality materials such as cast aluminum, which contributes at the same time also for cooling.

I have about 150pcs. built from these LED lamps, so far only one lamp has failed.
