Review on 🔎 F13T5 CW Fluorescent Counter Pack - Optimize Your Search by Centerfold Montague

Understanding the possibility, I checked mine upon receipt. 5 out of 6 worked, 1 didn't. Hence the deduction of a star. The light quality was on par with the Phillips bulb I replaced it with. Contacted Revain and they refunded me for the defective bulb. Revain will help you, just be polite and test them all within the return period so they can refund you. These issues can happen with such a delicate product, at least you don't have to go back to the store to replace a faulty product like I should have done in the past.
