Do you know auto off bulbs clearly?

In this letter, I would like to explain to you auto off bulbs as below.

All of our auto bulbs are using “anti-uv quartz glass”, so life time is very long.

Our customers test our auto bulbs many times that they are about 800 hours.

Meanwhile, most of our auto bulbs are with CE, EMARKS, DOT and ISO9001.

In order to make you clearly our auto bulbs, I will show you pictures as below.

Hope you can discuss with us auto off bulbs at any time.
