H4 Ultinon Pro3021 LED Headlight Bulb for Car and Truck -12V / 24V, Cool white light of 6000 K (LUM11342U3021X2)

This is the best led for less than 2500 rs. Much better than chinese leds who claims 100 watt 200 watt but totally zero. I fit this philips led [h4] in reflactor housing in my celerio car, the brightness and focus is best in both beams. No glare to upcoming vehicles, vision is enhanced after using them, I fix 100/90 watts halogen before led, throw is much better now with this led. Fully recommended. U can check it

Quality is good. Something you can expect from Philips. This Led is not for someone who expects bright light. It is just 20w so expect low brightness. May 20% better than Halogen but lifetime is more compared to Halogen and its white. I find high beam is much better than low beam but this is good for city drive. Also used in reflector housing and very less coverage in reflectors while using low beam. Purchased this for less than 2k so its worth for the money spent. I would have been disappointed it i spent more. Better than ultinon access which is 5k plus.

Less visible in night and special in rain season can't see properly on the road ...

Good

Excellent beam performance in reflector housing, total value for money compared to the Ultinon Access models which are just bad.

I have installed Osram H7 in low beam projectors and bought Philips H7 for High beams reflectors. My observation: 1. Brightness of Osram H7 and Philips H7 outside headlam lamp unit is almost equal. 2. Light throw of low beam or high beam is poor with Philips when compared to Osram. 3. Bulb design of Philips is culprit here. Because of thick aluminium frame (probably for better cooling), light reachability of reflector is poor as compared to Osram. 4. Fan speed of Philips is low as compared to Osram because of better heat dissipation but results in low reflector reach and poor light beam. 5. Solution to this? I filed the bulb frame. There is now a marginal improvement in high beam. 6. Conclusion: Osram H7 is way better than Philips H7. 7. Dimensionally, Philips are longer than Osram due to which headlamp dust covers were not closing and I had to make major alteration to dust covers.

Its light and focus is double than halogen but not too much like chinese or 100-150 Watts per led bulbs. Its quality is focused on lumileds technology which provides better light in low watts with focused light only on roads. It performance is very good in high beam and good in low beam. If you need very luminous led then go for 5000 lumen per led means, it has 1,500 lumens lumileds. But good for incoming vehicles. Philips ultinon 9000 is best if need super brigh light or Osram 50/80 watts per led headlight or Carzex smart Ai led light solutions.

Excellent
