Be sure to buy decent quality LED bulbs.

I tried some Titan 7-LED bulbs & they all failed quickly - some
within a week and others within a month or so - I did get a refund.

I'm guessing it was poor quality control at the factory & imagine
they are either out of business or else fixed the problem.

They were new to market at the time.
