There are no halogen bulbs for automotives that are rated above 150watts, and that can be used in specified reflectors only which can withstand that much heat.

Please stop comparing cheap leds with the high end one. Prices are high due to their research and development. I'm using photums from a year and they got fan too. I have driven 40k kms in last year..I never faced issue with fan or anything. Cheap chinese leds aren't worth it unless you're keeping them in spare just for emergency purposes.
Who told you that led have that much wattage? Max wattage of automotive led is 35w max. For hids its 75w max.
