The burner in accordance with the description and adjust as hoped in my A8. The brightness is much higher than that of the year-old burners, which were built with me. You only have a slight yellow tinge which at 4300K color temp. was to be expected. The illumination is not perfect (slightly uneven) but for this price is OK For a week in use and so far satisfactory. At this price, I would again install even in a year the same, if necessary. Hope they keep as long ......
