Ipopped a couple of the earlier lower binned XHP35’s but the E2 and E4 binned seem to be able to take an occasional 4+ amp burst but I think out put wise top out at 2.7-2.8 amps. I have been running all 8 different XHP35 E4 and a E2 builds 1 at 2.5 and the rest 2.8to 3+ amps and only popped 1 using a early RMM Buck driver, suspect voltage/current ripple, replaced the emitter and it’s still running fine so far. I have been running RMM’s e-switch 4S Buck drivers and Neven’s 4S LD-2 M2 Linear drivers. and using the K70 4S battery carriers.
Any of these emitters can be or are fragile up close to their peaks, so some current ripple or spikes at turn on can be damaging. This is where a quality driver makes the difference. I usually use Neven’s LD2 with the proper components for 4 series cells. The last one I built that’s doing 2.42A is a Buck driver from Richard that I asked him to set that way.
Fine tuning by hand with careful attention to detail is what makes the difference for most hot rodded lights.
So the stock TN42 driver would preferably be swapped out with an LD2 or the RMM buck driver? I’ll probably be needing a K70 battery carrier in that case?
sorry to have to bring this up again, but this is really bugging me. I just got some Zeiss lens cleaning spray just for my TN42 and wiped the lens with a lint cloth from the centre outwards, but i can still see a whole lot of smudge looking from the side, whether i wipe it just once or repeatedly. Just don’t get it, isn’t it supposed to completely restore the surface to complete original cleanliness? Did i use too little or too much? I sprayed once on the cloth close up.
I welcome you Newlumen.You are always respectful and easy to get along with.
As far as Greta and ~ 30% of “Vinh’s Minions” go, I chose to leave CPF for good. It was the easier softer way! that has NOTHING to do with Vinh as he has always been fair and generous to me.
why wouldnt you be welcome here?
your not a braggart, a self proclaimed prophet , :student: , ughh :person_facepalming: :person_facepalming: …… , or a know it all
of course your welcome here my friend
Hmmmm… more spray like no doubt said. As well as good cloth… finer the better.
I use the Zeiss spray too, but I mist the lens with it and then clean in a circular rubbing/wiping motion with a bit of pressure… turning the cloth to a dry spot towards the end.
Never had a problem so far. Clean & crystal clear lenses every time. :+1:
That TN42vn looks awesome! Is that Cerakote? Think I read vinh is offering that now. It's like an Arctic camo...
Also good to see the dedomed XP-G2 S4 gets some decent #'s, certainly better than the XHP35 HI can do, but not my much - think vinh's does ~790 kcd. The beam must be like a laser though - maybe some don't like it so thin. Wonder how the beam compares to a smaller thrower with a dedomed XP-G2 in it. Is this your first dedomed XPG2 light?
I had vinh mod a Crelant light for me way back, before I got into modding, back in 2012 I believe. Now he does it full-time and makes a good living from it, and lots of happy regular customers.
I guess performance wise it could be better , if instead of 4P batery carrier & fet driver configuration had 2S2P battery configuration & a mtn buck driver , it would give at least 10% up in the results due to the high Vf xp-g2 …
Vinh is perfectly capable of tweaking or replacing drivers. He works with Richard on custom designed drivers, so anything is possible pretty much. Usually it's hard to find out exactly what he does in his mods though, but I'm sure he's up'ed the amps in that one, probably to the max.
Ohh. Then true, he could have, but might take too much time. He's on the clock with modding, unlike us hobbyists, where we may skimp on money, not time.
But I've seen some pretty good results with 4P setups, like in the BOSS1 - 4 cells definitely get more amps than 1 cell on these, but a buck would still do better. All depends of course on what amps he was able to achieve. Also wonder what XP-G2 he used, surprised he could get good ones still, but I don't know.
Thanks guys. First of all, I like this blf. Everybody is nice and knowledge. This tn42vn have a cerokote coating… vinh mentioned to run a Sony vtc5a on this light… I am assuming it’s for better performance and driver vnx2.
