150 W bulbs declared but do not seem as powerful as this. Unless the performance of CFL bulbs (fluorescent) decreases the rise, what is possible and what I do not know. In any case, compared to simple 20W supermarket, they do not really illuminate 7 times, far from it, as it would be normal yet to believe, given the figures ... Also, I ordered two bulbs, and one of them malfunctioned early (internal sizzling, fluorescent tube not activated until the end) and then began to work normally after several ignitions. Product therefore UNRELIABLE and difficult to consider using professional! And there is also a bit cheaper on other e-commerce platforms (but it is the cheapest on AMAZON, daring the other to the vendors offering more than double the price "Andoer"!) Incidentally, "Andoer" is a reactive contact to the seller when a problem. Thank you to them.
