Since the ordered Led light bulbs from China (Hong Kong) are sent, I had adjusted to 2-3 weeks waiting period. The lamps were but after just over a week since. Structurally, the lamps were good, except for the front cover glass. The SMD - LED, s were exposed. That I do not see as a disadvantage. Unfortunately had the lamps not the values that I had ordered. Property me then agreed with the supplier via e-mail, took the lamps no longer be returned, and got a partial refund.
