This video is about Side by Side TEMPERATURE comparison of Philips Luxeon ZES H4 Head light VS Philips Lumiled MZ H4 Head Light.

My conclusions :

The Philips Lumiled with MZ chip Head light with Fan Heat dissipation is good, generates very less amount of heat when compared to Philips Luxeon ZES chip head light with removable heat sink but no fan in it.

The philips Luxeon ZES chip H4 led head light Generates high temperature up to 75+ degree centigrade, But its low when compared to HALOGEN bulb, Which reaches 90+ degree centigrade at the same period of running time.

We can see the the heat transferring to the removable heat sink is at good rate

Due to this over heating in ZES chip head light both filaments cannot be switched on simultaneously ( FLASHING High Beam only ).

Thank you for watching, If you have any questions please comment below i will reply you.

Have a Great Day...
