Based on the testing result, clearly none of those bulbs emit brighter light than MTEC does. Why? Don't they use the same CREE Chips? Are they not 20W or 24W LED Bulbs? The answers are NO! On the bulbs we tested, one of the them use FAKE CREE chips. One uses the real CREE chips, but they are not the latest version of chips from CREE. So the chips do not emit as bright light as the chips on the MTEC do. Besides, none of them are really 20W or 24W as they claimed. So don't be fooled with the "Higher Wattage = Brighter Light" They are NOT true! Be sure to buy bulbs with brand names. All the Chinese made bulbs we bought do not have brand name on the packages. They just came in with plain box. Who will you talk to when you have warranty issue? 　 MTEC has been making the angel eye bulbs for many years. They are not ashamed to put their logo on the products they make. 　 Don't put cheap stuffs on your BMWs just because to save a few bucks. Your BMW deserves better!
