Bought to replace a humming fluorescent light bulb in a kitchen hood (quite a modern hood, 2015). This lightbulb doesn't stay on all the time when I turn it on, it flickers from time to time and randomly decided not to work. I have another 18" double sided LED that I use in my bathroom and I tested it on my range hood to see if it was a connection issue and it was clearly a design flaw of the lamp. If it works, it's great. It's very bright and I prefer other bulbs when it works. I estimate that about 1/10th of the time I turn it on it fails. Judging by other reviews, I most likely have a faulty lightbulb. I would suggest doing some more research before settling on this one.
