Reliable. Great price for two. Great results. Was a skeptic, but not now. - Been using for over a month. Great results. Spectrum is proper--likely excellent but not perfectly ideal, as none seem to be. I was skeptical at first due to the price and not being familiar with them. If the life of them ends up being typical, I would buy them again based on their spectrum and their price, their results, for sure. Tremendous value for one but you get two! I used to pay nearly double for the leading competitor brand for just ONE bulb.
