Got the Xtreme Vision bought because it was advertised with very white light. I have to say I'm a bit disappointed. The light output is indeed okay but the bulbs have an absolute yellowness. Has not much to do in my opinion with a white light. Previously held the MTEC bulbs in it and wanted to try what the "supposedly brightest" H7ER suck so. Will it expand again. For people where it's all about the light output, access calm. For those who want to have their light more white, it is a clear yellow tinge to recognize.
