So I have been running the same LED headlights that I have been posting about and I really, really like them a lot. (I am referring to the version with the cooling fan.) They are bight and clear. Love 'em.
No problems other than the flickering...but it is very very minor and not always noticeable but the company sent me another ballast, two CANBUS adapters (which are typically used for HID flicker issues...which I think will fix it) and to be cool about it, also sent me a couple of what looks to be LED T10 bulbs for my use elsewhere. I am sure I can find a use for them.
So I got curious and got an infrared thermometer. Turned my lights on and waited 5 minutes for them to heat up. Interesting results.
At the hottest point of the headlight assembly I could find externally, the headlights are 99.5 degrees f right around there area where the hood meets the headlight capsule.
To compare, I also checked my JWSpeaker fog lights (which do not have a fan). The temp of those was 115.5 degrees f.
So the fans seems to work. But my curiosity never ends...
I also ordered a set of the fanless versions that scostuart mentioned earlier in this thread. This weekend I am going to install one and do a night comparison. I will also do a temperature comparison so see if the heat sink is as effective as they say. I am also going to do a more accurate "outside the housing" comparison with all three versions (incandescent, fan version, fanless version) to more accurate. I will report back what I find.
As mentioned before in this thread, I previously ordered a couple of sets of connectors to solder in for the new fanless version. Turns out I didn't need to...the kits I received had the right connector already. They must have changed this in production.
Stay tuned, I hope to get to them testing this weekend!
