Sounds odd. That led is mounted to the driver, so it should be getting real good connections unlike the seperate switch on the early Q8’s.
Normally I would say pop the driver out and touch up the solder contacts on each side of the LED, but the glued bezel makes that pretty hard to do.
Since it was flickering, I guess that rules out that it accidentally got turned off in the UI. I remember that happened to some people on a different light and they reset the firmware back to default and it started working again. That’s a very easy thing you can try just for the heck of it.
Teacher, fwiw… that 789D fully loaded weighs some 715,000 lbs. The tires are 12’ tall and weigh 6640 lbs EACH, there’s 6 of em at a cost of near $50,000 each to replace!
. . . . … Now ‘THAT is a TRUCK’!! A very expensive truck.
Good info Dale.
I wish I owned a couple of those & could have them working 24 x 7 x 365…. that would mean a lot more $$$$$.$$ for lights, guns, fishing toys, & trips to exotic places to use them all. :sunglasses:
A protected cell won’t run the GT mini the way it’s intended to be run though, best results come from a non-protected high discharge cell. The driver has built-in protections so everything is still safe and secure.
Sure, a protected cell will limit performance, but The GT-mini is an XP-L HI light that was originally specced with a ~4.5A regulated buck driver. The impact is going to be less significant/obvious than it would be with a triple, or something with a low Vf emitter.
It looks like the difference between the protected and unprotected versions of that cell are ~10mOhm. That’ll be, what, maybe 10-15% of output? It may be unacceptable when hot-rodding, but hard to notice in practice.
(Keeping in mind that the tires are 12’ tall, a pickup truck comes about to the axle and is completely dwarfed! The pickup is about 6’ wide, this monster is 25’ wide! The pickup weighs what, 4,000 lbs? Loaded with rock the big hauler weighs an impressive 715,000 pounds! [215,000 lbs of truck, 500,000 lbs of rock] The tires are 6,640 pounds of rubber, not mounted to their 57” steel wheel!)
PS: A 4 year old used one, which has probably been running and hauling rock 24/7/365, cost’s around $3,000,000 dollars. And it will take $2,000,000 a year at pump prices just to fuel it with diesel! The 1,000 gallon tank lasts 12 hours, two tanks of fuel a day!
Illumn’s site states that the Keeppower 3120mAh protected cell is utilizing a Sony VTC6 inside, with a maximum continuous discharge rate of 15A. This cell should run the GT mini’s XP-L HI just fine. MOST protected cells can’t.
When you can get a Samsung 30Q for around $5, paying $12 for a protected cell in a light that has internal protection built in seems kind of wasteful.
Haha, it was. Oil field work before GPS and cell phones. Most of the gravel roads weren’t on any maps. All we had were someone’s directions to a well that we had to work on. We got lost, “hey there are some vehicles over there, lets go ask them”… The headlights on those trucks are mounted quite low, so you don’t realize how big they are until you drive up next to one. Of course they were moving so we were trying not to end up like this.
Lord have mercy! (but that IS what I was thinking when I suggested the CAT scan. lol )
The driver sits about 15’ in the air, on the far side of a 25’ wide vehicle. He can’t see much of anything on the right hand side, like that pickup that put himself in a bad place. Nowadays they have 360º camera’s with monitors in the truck, but still….
