Could you inform me what’s difference between auto halogen bulb 042 and 041?

Although my factory produces auto halogen bulb for a long time, I don’t know clearly 042.

Манай 042 галоген чийдэнгийн ихэнх нь “UV эсрэг кварц шил” ашигладаг.

So our auto halogen bulb 042 has best heating dissipation.

And the life time of our auto halogen bulb 042 will be about 800-1200 hours.

Meanwhile, our auto halogen bulb 042 plug and play.

Due to we are manufacturer, the price of our auto halogen bulb 042 also very low.
