No worries, and I didnt take it that way. Nothing implied, and the improper heat sinking/poor thermal path has historically been a repeated complaint by many sup/acebeam owners. If a 3 minute light fits your needs without complaint, then you’ve probably got a decent light as long as it doesnt cook itself, the driver or the cells.

If you want a similar light cannon with XHP70 that can sustain longer run times before meltdown, my best advice would be to wait. We should soon see many new large reflectored offerings with XHP emitters from other manufacturers. If you need something amazing and immediate at the 5k lumen level and above, Id probably take a close look through some of the custom build threads and consider asking a member with a long history of success if he would consider modding or building a creation to fit your needs. Old Lumens and RMM are innovative (amongst many others who mod & build).

If you start a new thread and ask the forum, Id be happy to add my 20k lumen ideas (which are realistic and fairly simple to accomplish), and you’ll probably also get a great amount of qualified advice from others who are more than happy to see your dream light come true.

Yes. High power doesn't come without heat. :)

However, I don't fully agree on the poor thermal path theory. A poor thermal path would lead to emitter (and/or driver) overheating, which would lead to heat sag. But there is no significant heat sag.

I ran four tests to prove that, and came here to show the results. Tests were performed indoors, with ambient temperature of 25°C.

Test 1: 10 minute run indoors, light left to stand on my sphere, without any cooling

Temperature (in warmest point = around the control ring, between the emitter and driver) did rise to 71°C. That's hot, indeed! Please don't leave the light running on high unattended.

However, even when being this hot, the light didn't show any major heat sag.

Test 2: Cooled with a small table fan on lowest setting (About the same as using the light outside with some wind)

Temperature up to 53°C in 10 mins. Way better. Heat sag almost nonexistent.


Test 3: With ultimate modern liquid cooling device (read: my hand ) - with hottest cells I had

Temperature became steady at 50°C. Hot, but not too hot. Again, almost no sag (heat, or whatsoever).


Test 4: Full runtime test with light breeze (same table fan as in test 2)

Max temperature during the whole test was 62°C. Yes, that's hot, but acceptable. No evidence of heat sag.


My conclusion: Featuring a very hard driven XHP70 emitter, this light gets hot just like a hard driven light should. No evidence of poor thermal path affecting the performance of this nice light.

Ps. K60 does have also lower modes which allow running it unattended without fear of too high temperatures.. ;)

Hi AlexGT. Could you elaborate on the tint, please?
I hope it’s not too cool, compared to say… the 5000k MT-G2 tint
That would be a deal-breaker for me :expressionless:

136

I'm not AlexGT, but I'll try to answer anyways.. ;)

The tint is more neutral than a typical cool white, but not even near a MT-G2. Maybe somewhere between 5500 and 6000K?

Here's a mouse over comparison (mouse over for K60):

137

Thank you, the for the info and the pic (btw… how do you pronounce your name?)

I really don’t mind tints that are a little cooler than 5000K but certainly not those in the 7000K+ range
Especially those with a slight pinkish/purplish hue :frowning:

I have the K40M myself, and I just love the tint.

138

I hope the “Convoy L2 2015 version” isn’t going to be vaporware like the Blue Convoy S2+. It would be awsome if it had a XHP friendly reflector.

I believe it’s about at 6500k and at lower settings it s a light cool blue but turbo and high it really whites out once higher amperage

140

the nice graphs thanks for doing them, very interesting.
I really like my K60 and don’t regret buying it. If the torch is getting hot quickly then isn’t the thermal path doing its job well and removing heat from the emitter? I would be worried if it wasn’t heating up.

141

looking at mine and waiting for dark every night, I was gifted some really wow factor lights I would never be able to get ,and I now have a k40 which I love with mtg2 and also the x60 which when I try to describe I cant,I mean there is no hot spot ,and it’s deceptive because it lights up like a mega flooder but the wall o d light just keeps going and going lol.

Full review finally online. Sorry that it took so long, but I wanted to be very thorough with this wonderful light.

Well, FP gets a lot of crap about Ace beam hating, but a lot of what he says is true. I hate Ace beam and would never take a light from them, even if they gave me one. I think they can make an attractive looking, somewhat functional light, but dollar for dollar, they are very overpriced and under engineered, or maybe over engineered, with not enough engineering experience. That's just my opinion. If people are happy with their lights, then that's all that matters for them, but the fact that Ace beam has a history of screwing with people should not be totally forgotten just because the light is "DAMN BRIGHT!!".

145

Well, to be fair to AB, only their current crop of rechargeables are having problems, and should not be unfairly lumped together with ALL their models.

Taking aside their multi-cell rechargeables, AB are making very nicely featured and engineered light model offerings.

146

So no GB for this ? :stuck_out_tongue:

147

Most definitely not. :stuck_out_tongue:

148

Yeah since Acebeam blacklisted us BLFers for buying their products below MSRP :frowning:

149

please don’t.

they shut down another source…

150

If that’s true that’s absolute sh!t.
With all the internal charging issues with the X40 and X60 THAT STILL AREN’T RESOLVED they should be doing EVERYTHING they can to be making us happy for Gods sake, not blacklisting us so we can’t get a discount on their products that only half work.

I was about to buy one of these, now reconsidering.

151

Please explain what happened?

152

Are we sure that it’s just us BLFers being shunned or a new global policy from Acebeam against MSRP discounts ?
