Pretty much sums up what I’ve been trying to explain to people too. Knowing how ridiculously good yours are (and the other issues) is why I keep telling people that although the purely machined SS collars I’ve made have gotten to the point of around a 25% boost in the 1405, it’s still a far cry from the 80+ you’re getting from your optical systems. I’m sure there is still more tuning that can be done in the micro metal RA’s, but getting to 50 boost will probably require a cost equivalent to (or close) to the RA’s you’re making, if it can even be done.
By the way MEM, I’ve been meaning to text you back. Been a busy last week, but I think I’ll have some time today to finally get back to you.
So on an aspheric head with twist zoom glass lens can the
XP-G2 S4 2B dedomed at 3.76 Amps in Turbo or High Mode hit 1200 or more meters of throw for the ‘white laser’ effect…and still be useful at close range using flood ?
Who would build this ?
Can it exceed the Dereelight in throw ?
I think a fixed Aspheric is less useful and versatile than a good twist Zoom.
Hi robertkoa, you did inspire me to redo the mod properly today, but it being my farthest thrower still, I’m reluctant to part from it.
I may re-mod my second 1504 (which is a shortened 1405) one of these days with the same parts and then sell one to you. As for the costs, the parts were about $50 altogether and shipping to the US (?) is $27 with tracking.
Anyone have beam shots of these lamps as in the thread title?
I have just received two 1508’s with 75mm glass ( both broken edges) from Shenzhen Homesafety Electronic Co.
The lenses still fit and are not cracked in the middle, only around the mounting. They are sending me new lenses.
Those glass aspheric lenses for flashlights are all made in a mould, not ground to shape. Therefore they all have to some extend surface irregularities, it is hit or miss how much, it is very far from optical grade and even my Sunwayman aspheric flashlight clearly has a less than perfect lens.
You must have one of the worst examples of them all, or perhaps all the 75mm lenses in the 1408’s are exeptionally bad quality.
Btw, the maximum flood on your light looks ectremely narrow.
Yep very narrow.
here is very quick un edited in camera jpg shot indooss just now on my bed.
I have two of these , identical, one is set to max zoom, …just about to drop off the thread, the other max flood.
I have shot a load of others, of the pill etc, that I will put up on the other thread I mentioned earlier
OK, so they have sent me two new lenses…DHL on their way.
So the recommendation seems to be an XP-G2
what is the max safest current I can drive this at? I see 4 amps being mentioned before, but was this with any specific cooling? more than the ‘standard’ pill to body heat transfer?
the pill is brass, but with collars on it, so not maximum pill to case heat transfer unless I may be fill the groove with compound. and the thread also?
Any one recommend a buck driver that has NO components on the spring side? 17mm have up to 22 mm depth in the pill.
Like to run 3 series lipo Cant see one on Mountain Electronics, and a brief FastTech search did not reveal any either.
17mm buck driver, 3S input, 4A output, no components on spring side. I think that's something that doesn't exist! The pill is brass so solder something in.
Funnily enough I did solder one in on another pill, but though I’d ask the question , as screwing it/clamping ig with collar is so much easier if things go wrong
OK, then so can you point me towards a 3s buck driver in 17mm J can solder in that gives 4-5 amps
XP-L V6 1A
Hot Dedomed – 107900 lx at 5.82A for 361 kcd
XP-G2 S4 2B
Hot Dedomed – 137000 lx at 3.76A for 458 kcd
XP-G2 S3 1C
Hot Dedomed – 127000 lx at 4.05A for 425 kcd
Can someone help me understand why the hot de-domed XP-G2 is so much brighter than the XP-L… despite drawing less current? Aren’t these two emitters using the same die?
