I had a set of the laser blue bulbs from halfrauds. There a white light, Not blue/white light. There good but not worth £17 per bulb.
Ive got the Halfrauds Super Brilliance bulbs in at the min coz they were buy 1 get 1 free. otherwise £24 per bulb. !They are better than the laser blue ones but cost alot more.
Overall i think the bulbs are good, just not worth the money they charge.
