the newest craziness 9x XM-L U2

In every multi-LED app that I've seen in a single reflector, throw is compromised.

I have made (or purchased) several in varying sizes, all the way down to twin XPGs in a single P60 reflector ("Linger Special")

Due to packaging, none of the LEDs are optimally positioned in the reflector. This is seen in the relative lack of collimation compared to the S1.

Hi Joe,

It seems that they are driving each at about 1.8A thereabouts, to do 5000L out-the-front (calculated using the excel LED output calculator that you can find here on BLF). That's from my calculated guess on the ceiling bounce on the lux meter.

Also look at the temperature rise, even with the high mass of 1kg for the light/fins, we are doing a delta of 31 deg C or 16 deg C rise to 47 deg C for a run of 10 minutes. XTAR S1 is 18 deg C delta and SR92 is 19 deg C. I have seen the Xtar S1 in detail, no way that it or the SR92 has a lousy thermal path from the MCPCB to 6061 host.

You mentioned 2A vs 3A. For info : 1.8A = 658 lumens @ emitter (cold), and 3A = 937 @ emitter (cold). 5 LEDs x 1.8A = 9A = 3290L emitter and 3 LEDs x 3A = 9A = 2811L emitter. That's a 17% difference. I guess it's not a lot but that's not insignificant as well. Esp if you are pushing the envelope....

I just want it to be cheaper....

Haha...nah i just know 3 languages. English, Chinese and the Cantonese dialect. I know a bit of Hokkien, that's all.

Yes, the range is MS2010...they have several hosts like 2D60 and 2D80 (probably denotes the head diameter).

HKequipment.net used to carry flydragon but they stopped. Here's another one : http://www.ebay.com.sg/itm/Flydragon-Fei-Long-MS2010-SST-90-SST90-LED-Flashlight-/110830649774?pt=LH_DefaultDomain_0&hash=item19ce0581ae

If you ask me, it's too expensive though. Check out the GB in shoudian for the China folks, it's not very expensive.

I guess if anyone is really interested they can ask HKE. HK is a good place to start, they are so near to Shenzhen. It's like our country here crossing over to Malaysia's....just over a bridge. City centre to City centre is just like 30km.

That's a good idea. If we swap out the 5 x XM-L in the TR-J12 to 5 x XP-G i'd estimate that as maybe 35k cd range and calculated @ 1.5A you'd get 2000 lumens OTF, just a slight drop in lumens. TR-J12 is 24k cd.

There is a 3 x XP-G budgetlight, you can see it in ebay, but it's not very popular. The reason is probably just that, XP-G does not sound impressive for the general folks/beginner flashaholics.

I kind of agree w/ you bobk - I mean, when you walk outside in daylight, you're not shocked...so how shocking can a flashlight be.

on the other hand, maybe you could try taking your big 'guns' back out and standing down range from 1, then down range from both and the difference would be more noticeable ;)

now it's available at intl-outdoor.com, the price is ridiculously high

Most of you probably would not be able to see the characters unless you have chinese support, but they had an offer for the first 10 guys in each 4/5/7/9 XM-L category, think it's a special price and free battery. The next 10 guys would be special price but no free battery. After than full price and no free battery.

They have U2 and T6 3C options.

9V protection and 6.2V protection for 3D and 2D respectively.

Anyway I'll just post there webby here. http://www.feilong.us/

For more pictures, pls go to shoudian and see post 2 by Feilong. I am posting just 1 pic here from my gallery as I think they don't want people to hotlink direct from their site. (bandwidth probably)

My parents will be in Shenzhen/Zhuhai/Guangdong next week but I don't think it is cheap over there even with the help of my relatives. LOL!

For me i'll be in Beijing the week after next....but i think nothing much to buy as far as flashlights/lxxxx are concerned.

lol. You would not see me having 9 18650 batteries in that light! And some people are afraid of 2-4 18650s in one light.

Since it at has 15A max current. That would be 1,67A to each led. So theoretically it should be about 600 lumen on each led. 600*9:5400 lumens.

Probably a nice light if you want 5000 lumens from three 32650 batteries paired with long lasting LEDs. Very expensive tough.. Way too expensive! Altough it is probably the sickest XM-L lights out there! So with no opponents it kinda can justify its price.. Only people with way too much money will buy it tough. Lucky ba... ;)

btw.. would it not be better to just buy a 55/65w HID if looking for a 5000+ lumen light in that price range?

(no clue about HIDs, or what price range decent lights are.)

Probably it has low 5000 lumens OTF. My 65 watters gets me approx 3800-4000L OTF. (difficult to measure because there is an optimised burn position which is not vertical, so a ceiling bounce gives you a reading that slides down). The 85W might not even touch 5000 lumens OTF....still plenty bright though.

Don't bother with the wattage though. Measurements are better. One thing is that it's extremely difficult to get a current reading for those aluminum flashlight host HIDs that you see on Ebay/Aliexpress.

A 100W ballast @ 24V input with 100W bulb (just for measurement's sake, coz 24V it has higher efficiency) can net you about low 7000 lumens OTF on a 6" reflector with the thick glass lens intact (cuts about 11%).

To look at this from a more different perspective, I have a total of about 37000 lumens OTF from the HIDs. (conservatively speaking, > 30000 lumens OTF, confirmed).

Be fun to review something that outrageous. I guess they got any heat issues sorted, right? I can turn this thing on high without losing an arm?

Damn . . . . nine XM-Ls.

wowFoy

The "problem" I see is the throw is not apparently huge for that power consumption, and I feel a big part of it is not usable for flood either, with much less lumen output you get a more than usable light dimmer but enough.

I would like to see a light with 3-5 XM-L with deep and not very big in diameter, it might be a better compromise between flood and throw (at least in my head).

Exactly what I was thinking as I was reading this. I like bright torches, but this is getting into the league of having to wear a welding helmet so you can use it and not damage your eyes!

“I wear my sunglasses at night, so I can, so I can,” turn on my torch without going blind!

Awesome lights though :open_mouth:

Hopefully this’d be more affordable, 5 XML mega close together. One for throw the rest for flood 3500 lumen high

I actually have the 360CSM Flydragon. Wall of light with big flood. It does have some throw however it is visually lost due to the area lighting affect. Yoy can run it for the life of the batteries- it doesn’t get too hot. Excellent build quaility- not a cheapie at all- professional finish. Biggest draw-back- leave the batteries in, it will drain them in less than 2 days! I think it will be the same with these multi emitters, and they will all be big flood lights. And heavy!

$400? Dang that’s out of my league

Just wait until these kind of lights are available as budget brand :d

Its 50 bucks cheaper at HKE.

Awesome, I love your design-built, about 10 ideas, innovative. :smiley:
