HID Car Headlight Bulbs Marketing BS
Posted: Wed Nov 28, 2018 12:19 am
I've finally bought a new pair of D2S HID headlight bulbs for the Volvo seeing as the drivers side one is now very pink and so dim it barely lights the road up, and boy, as it turns out, buying HID headlight bulbs is very difficult when all you want is facts and figures & not marketing BS.
I mean take a look at the pictures below:
* Brightness up to +70%, 7 dashes vs 4 - Yeah I eventually managed to find the lumen value for this bulb and it sure as hell isn't +70% over an OEM equivalent bulb
* Distance up to +20m, 6 dashes vs 4 - Right how'd you work that one out?
* Light colour up to +5%, 5 dashes vs 4 - This lamp is 4350K after doing some digging. So it's 5% cooler than something warmer, so what?
* Life time, 4 dashes vs 4. So what's that in hours??
As you can see most of this is marketing wank in its purest form i.e. complete twaddle. It's often quite difficult or even impossible to find very basic values such as lumens, expected lifetime of the lamp (in hours) and colour temperature. I haven't found any information on CRI or lumen maintenance for any bulbs I've looked at.
Oh and don't get me started on the cheap Chinese lamps available in colour temperatures up to 10,000k. Might as well just stick a blue LED in instead.
