****s, false advertising. Do not buy rechargeable light bulbs.

I bought 4 chargeable light bulbs at one day only just over a month ago. They advertised that the light will have full brightness for 4 hours. Wow. Just in time for stage 5 at the time. But just after an hour the light gets very dim. It never came close to the 4 hours as advertised. Now not even 30 mins and there is barely any light. This is false advertising and a total *******. Never again will I but from one day only.... Just a bunch of ****s. What a waste of money.
