comparison to 55watts ???
its time i share some details on the light and why i ordered it after checking every bit of info with the owner/seller of the firm. he is now a good forum friend of mine.
the H4 bulb is a direct OEM replacement. hence fits directly . no mods whatsover however ... however i had to cut the rubbeer boot by .5 cm on sides which does not affect the safety/dust protection or anything at all.
coming to power :
the bulb uses 4 cree beads which is each 10 watts - hence 40 watts in total.
Low beam engages only 2 LED- using barely 20 watts - making roughly 2000 lumens
High beam engages all 4 LED beads using just 40 watts - making 3800 true lumens and not claimed. if going by chinese terminology claims it might hit 6000+ lumens theoritically as each bead is capable of delivering 150 lumen per watt.
Now heat dissipation :
its not just a heat sink but it has a High speed fan as well which engages via its own temp sensor as and when needed and stays out of the bulb assembly.
it is 100% water proof . tried and tested offroad, crazy rains and extreme pressure washes from all direction.
heat/reflctor melting : even after 2 hours of usage unlike the standard bulb you can touch the glass of your headlight assembly and its stays cool just like with the headlight turned off. no heating never....
power : stock bulb uses 55w low and 60 watts high beams. this is barely 50% power.
