Yes, pretty impressive what one led can do against 5, the k60 head is a tad smaller diameter too.. Overall an excellent choice if size and /or price is a considerable. No on board charger, but seems they are not recommended anyway unless an emergency, and no cool case, but there is a nice belt holder... Pretty amazing from a small light.
But Vinh steered me right when I said I wanted most throw and best beam regardless of price.. It really wasn't that much more.

I haven't played enough but so far I'm thinking if you really want to run much turbo, the x60vn will be much better.
It's nice the smaller k60 has muscle too but I'm guessing on a one minute period I had them both on the head of the k60 was maybe 50 percent hotter, so I'm assuming 5 minutes would be one hot tamale!
Both of these lights are major players and so produce heat, long term use will be best at lower levels....
But the beauty of it, the human eye adjusts to the lower levels and you have turbo just to make sure!
I thought my sr90 was bright and it's always been enough and not until I ran them side by side do I see the real difference in 2200 lumens verses 6000.
Don't get me wrong, 6000lm is sweet but it's really not needed for long term use. Everything close is blinding to look at the point of not being realistic and you have to squint.. Only great distances where its needed.
If your going to need a searchlight on your boat etc that stays on extended periods, the x60vn is better IMO but for practical use and ease of carry the k60 is great.

I'm sorry, I meant how long on turbo do you think you get with the X60vn? From just last night, I'm guessing 8 to 10 minutes and then throttle it almost all the way down. It was still building heat at around 75%. It was also about 88 degrees so maybe that plays apart but I'm not sure. My X60vn is fully loaded so I can't imagine how quick it would heat up without the heat sinking.

Re: X60vn 2015 - Lumen & Throw
No doubt, mine is too! I can do a test if you would like, I think Vinh got a little over 5 minutes on his but I think the real thing you're looking for is what is the magic level that stays constant and no longer gets hotter is that correct?
It might take a thermometer to test that one!
No matter what level it will always be warmer than turned off obviously, but I'm sure there is a level that stays constant and never rises about 120F, when other levels stay constant under 1500 etc .
Maybe the real thing we must decide is what's an acceptable temp to run constant and go from there.

Well it's a good thing to feel it get hot, that means the heat sink is doing its job!

Re: X60vn 2015 - Lumen & Throw
I agree, I just wanna know what's safe. I'm gonna use this thing quite a bit and I don't wanna damage it. I'm gonna do an unscientific run time tonight if the rain holds off. The thermometer is a great idea too.

Seems I remember Vinh saying if you can hold it without gloves your good. Not sure if he was specific to the head or the handle

Zebralight SC600 II MKII W is PID controlled and run at 124F max. Sounds high at that temp, but it's not painful. I think 124F is a pretty good temperature cap. Anything more would be painful.

Re: X60vn 2015 - Lumen & Throw
124º F as a SKIN temperature is enough to cause actual damage. Skin temperature over ~ 112º - 115º F will be able to cause conduction burns.
The PID temp is internal, and there are losses on the way out, plus, your hand sinks off some heat too, etc...so, if a dozen or so degrees have bled off before the skin can get that hot, you're not going to get a burn, albeit it can still hurt/cause pain, etc.

Re: X60vn 2015 - Lumen & Throw
My temperature measurement was at the head, 124F, don't recall the body temp, but it was tolerable to hold. This experiment was conducted in a 100F engineroom, so ordinary circumstances would make the flashlight even easier to hold. I gave the light to a good friend =( so I can't run the test again to check body temp.

Re: X60vn 2015 - Lumen & Throw
So took the X60vn out tonight and got 8 minutes and 45 seconds on high until the rain hit. I figure I could of gotten another 2 minutes before it got too hot. The ambient temperature was 87 with high humidity. Here's 2 beam shots
Sorry for the poor quality. The first 2 are about 175 meters across the quarry and the last is 75 meters. This is the first time I have posted pics, I used my Galaxsy S5 with the ISO set to 800.
After running on high for a combined 14 minutes and low for 3 minutes the purple Efest 35 amp 2500mah batteries Vinh sent with the light are at 3.98V. They were topped off before hand. Any guess what kind of run times total?
I'm ordering a set of the Sanyo/Panny 18650GA 3500mah hybrids. Hopefully I'll see some good run times from them.
Another thing, the infinite adjustable ring starts at 10 lumens and I would guess its probably 100 to 150 lumens. Hopefully Vinh gets the hang of the light sphere so we can get some numbers.

Re: X60vn 2015 - Lumen & Throw
I would not use the iso settings. They are not very good in the s5. Thats what i use and for me when i need the most exposure i use the auto night dection mode with the exposure value to +2 if you need it even brighter. Its way better then 800 iso

The night mode in the S4 seems to make the pictures even more blurry. It started raining so I had to pack it in. I'll try again and mess with different settings. I'll get my daughter to use her DSLR when she gets back this weekend. I don't think pictures can do this light justice. It's just so powerful and the tint is just perfect for a searchlight. I'd like to see a comparison between it, the K60vn and the SR96vn. The comparison pics that Windstrings posted seemed like the K60vn was not too far behind the X60vn.

Agreed, not too far behind but the tint is another topic.
I agree the tint is perfect for a searchlight because it's perfect true to life.
If the k60 wasn't neutral I don't know how it would look, but maybe better if combined with dedoming. The higher kelvin will give the illusion of being brighter too...
But the bottom line is if I had to say which is easier to define an object from a dog, cat, racoon, or just a log would be the x60vn IMO.
I've seen many lights where the higher kelvin is "too" high and it becomes difficult for the brain to negotiate objects in the ultra high contrast between shadows, but the x60vn is perfect.. I'm guessing about 5000k.
The k60vn is more like with sun nearer to time of evening when the sun is not so hot, keep in mind that's a neutral led dedomed.

Yeah for the money that K60 is a bad mfer. My X40 fiat lux has served me well with 243,000 lux and 3500 or so lumens but I still think I'm going to buy a K60

windstrings - how big is the difference in throw between x60vn and k60vn, because in your beamshots it looks as if the throw was very similar. I ask because the x60vn has 600 lux and k60vn 230 lux.
You are asking what the difference is between 600k cd and 230k cd?
For perspective, lets say you needed to see if there was a trespasser on your farm, and, he was dressed so that you needed 1 lux to see him.
The 600k cd light would allow you to spot him at ~ 750 meters.
The 230 k cd light would allow you to spot him at about 460 meters....
....So having the 600 k cd light would be like having the 230 k cd light on a 290 meter selfie stick, to get it closer to the guy out there so you'd have enough light to see him.
😀
For long range beam shots, its VERY hard to show a difference at ranges that BOTH lights can hit, as in both, you simply see a spot of light....and, our eyes are lousy lux meters in real life, let alone when looking at a picture.
😀
The only way to more reliably see a difference is when one light's range allows it to be visibly brighter/reach the target, and the other light's range doesn't. When both can reach, it tends to look as though they might be similar.
In our above example, the 230 k cd light is putting 0.4 lux on the guy 750 m away, and the 600k cd light is putting 1 lux on him.
As he's INVISIBLE at less than 1 lux...we can see him WITH 1 lux, and can't with less.
The DIFFERENCE in intensity is roughly 0.6 lux at 750 meters. Our eyes are great at telling if they see something, or not, but SUCK at judging how bright two objects are relative to each other when NOT visible at the same time to compare.
