I got this budget Infared Thermometer on Amazon for number 5 heat test. Seems off. For example my wall seem colder than 72F and, my skin less warm than 88F, a metal surface I heated up that is burning to the hand was only 200F, icecream in the freezer at a low 17F. I guess worst case we will just use it as a guidance on temp changes rather than accuracy. I am sure someone here got one right? Are these numbers way off?
the wall could be right. you can try your temple or the inside of your mouth, should be >90
problem is two things though, these are terrible with taking temps on reflective metals and second where that laser pointer is and where it’s actually measuring can be pretty far off on something as small as a flashlight
By the way its crazy how much adrenaline I went through. Doesn’t seem much on video but I was crazy nervous and excited. Off camera we did a test run over a “normal” light and yeah it was crushed. That made me soooo worried!
I was thinking if the head got crush then I will be VERY screwed! I wouldn’t know what to do. Literal devastation. I am so happy we made it this far. In fact I couldn’t sleep more than 4 hours last night thinking about everything and what’s next. Whooo
The more LEDs you have the better the efficiency at lower levels.
Take the X80GT for example with its 18 XHP50.2. This light can run 4000L level SUPER LONG heat wise vs a light of similar mass running a single XHP50.2 pushed to 4000L.
More LEDS = Greater turbo lumen. Always exciting to push boundaries.
More LEDS = more enjoyment while the LED is ON or OFF Wink
This specific light engine will also be especially useful for photography, videography, diving, diffuse lantern, ceiling bounce, woods navigation, attics, real estate illumination…
Yes impact tests is very important and it’s test number 7. Still have 5 and 6 to do today though.
Actually running a 5100mAh 21700 cell with a quad white2 is no joke. The light will get WAY TOO hot to hold at some point and I am really not sure if the all the internals can hold up to the heat. 18650 volatge sag faster so the max heat period isn’t likely too long but 21700 should last a bit longer. Gotta set this up outdoor to be safe. Video will be boring to watch but the test is crucial to see how the electronics hold up.
Anyone want to guess how long it takes for the light to get to Too Hot To Hold?
With quad Osram CSLPM1.TGs I’m guessing 3 minutes or so considering the amount of aluminum. Of course too hot to hold is subjective, so I can see it being extended out to 4 minutes.
I love the X80GTvn I received from Vinh two weeks ago. I measured 28.9k lumens in the TA lumen tube but considering how lumen tubes measure flood lights lower than throw lights, due to some of the spill not being captured, and this light is like a mule, that translates to about 32k lumens or more. This is good boost considering Acebeam lumen ratings are usually inflated by a good amount despite their throw ratings are conservative. I am also impressed how this thing can run pretty much indefinitely on the 4000 lumen mode. It is MUCH smaller and lighter than the MT03 that uses the XHP70.2 and a good amount smaller and lighter than the MF01S but runs much more efficiently due to the number of emitters. It makes it extremely practical for indoor use and for indoor photography. Great practical worklight that I use for my inspections. However, X80GTvn is still a bit too big because I need both hands to stabilize my huge phone for picture taking while holding the light so a single cell 21700 multi-cell mule would be ideal for my work use.
Yeah my only concern with the 12-ish emitter setup would be heat. Definitely more efficient at a set output, but if the driver has a direct-drive mode that could get hairy with how much current the new high-drain 21700s can deliver.
I’m not the target audience for a mule in general though so I’ll let someone else figure that out.
