Lamps with an increased declared resource are usually referred to as LongLife. And do they really work long?
Za Rulem experts Aleksey Revin and Mikhail Kolodochkin took several sets of H4 and H7 lamps with such markings from different manufacturers and set out to find an answer to this question.
You can get a detailed answer a little later, but for now we will give only one result of their experiments, which will indicate which lamps you absolutely should not buy.
Products called Ca-Re Longlife H4 turned out to be the worst in the study. Just imagine: one lamp worked for only 670 hours (even for average samples, the resource is at least twice as high), and the second turned out to be completely defective!
Are there any LongLife lamps that are really worth their money? Read our article “LongLife lamps: do they really last longer? We checked and were surprised!”
