Because h1 bulb is very small size, I think h1 bulb is most difficult to be done.

H1 bulbs only have small space, but their lumens will be 1500lm.

So it’s a big problem for heating dissipated.

At the present, my factory putting high concentration halogen gas into h1 bulb, so they are brighter and long life time.

I would like to attach h1 bulb as below and then you can check it.

I hope our top quality h1 bulb can make you final decision.
