A Buck regulated 70.2 should stay cooler then a FET XHP70
if the heat transfer to the head is bad, the heat up of the light after some minutes is the same, just the LED gets a lot hotter
the power dissipation heats the light up anyways, a thermal resistance can do a delay, while a part inside gets a lot hotter than with better heat transfer
The MT07 seems to have a thermal regulation with a moderate temperature and the XHP70.2 runs cooler than a 70
Here is a Thermal image that I took at work.
This is after 10 minutes on turbo. You can see concentrations at the head but the heat is moving out and away... Temp is set to Fahrenheit.
The top right shows the the highest temperature for the entire time the gun was active on target.
Instead of targeting the fins I targeted the area at the shelf where damage could occur if the heat is not controlled in some way.
You can see that after 10 minutes the highest recorded temperature was 118 degrees F and just a few seconds once thermal protection.
I was really supersized how well it controls heat even before thermal protection.
I want to get another shot and record the entire reading.... The problem is that this is a Fluke thermal gun and the company owns it. Allowing me to test it was not to hard as I have been there a very long time. Getting permission to have any kind of video taken in that area will take approval from about 4 different managers.
LOL they do not even know how to use the gun or even what we use it for but they still make the decisions...
Before anyone asks lol.. The date has not been set on the gun in several years the other information is all correct.
here is my mod of this light.
I can now say that it does heat a lottttttttttttttttttttttttttt i mean after 1min in turbo mode i can not barely touch the head.
Output is twice as the stock light.
Thread with pictures of the modding
Sweet... I'm at work so can't watch the video. I will watch it when I get home in the morning.
If you doubled it I bet it does get screaming hot...
Hello mizou51,
it seems, that the images, which were shown here, are not accessible anymore. Can you please edit the original post to contain these again?
