In order to guarantee this in the long run, I let my "230V RoHS 5500k 26w" burn nearly 1000h.
Surely this would be a clear statement of an electrician's more than welcome.
Hope I could help you as far.
Oh, - the set gets to me:
1ter star for the price Power / Lighting
2nd star for the pack size or carrying option and stowage (carrying bag - round head does not fit in)
3rd star for the quality of the items also hardly weight (bag Ne milk (1kg) weighs more)
4th star for the Long Cable (about 260cm)
5th star for the low heat (after 1h was the Risso's much colder than my palm)
6th star for the barely perceptible odors and decaying to the tendency towards zero
One star deduction for the excessive shipping package. Since going with less significantly more.
One star deduction because the round head was dented slightly
However equalized again, because he is very easy to get back into shape.

General, - as I said 5 star buy recommendation
