Good morning Sir and thank you for your message about H7 Bulb sainsbury’s.

I think H7 Bulb sainsbury’s shall be big quantity.

Because sainsbury’s is one of biggest chain super markets in UK.

All of our h7 bulbs are using “Anti-uv quartz glasses”.

And our h7 bulb is real long life time.

For example, our h7 bulb will be 800-1200 hours, which is 3-5 times as long as others.

If you use our h7 led bulb, the life time will be about 30000-50000 hours.

Please don’t hesitate to contact my H7 Bulb sainsbury’s at any times.
