I order from this seller, this company is the third pair of lamps, all different, put p21 in DHO (yellow) brighter than the standard ones definitely and shone in quality for a year and 3 months, then one began to burn out, but not all at once, I think the result is worthy (mileage about 25-30 thousand), I put the overall ones even earlier than 6 diode ones, they still shine, these checked-they work until I put it. If you want quality, it is better to overpay a little, and not fight flicker and replacement every couple of months.
