General discussion P60 host issues

Yes your right i have never thought about a diffusor, all i see are filter lenses over at ITC..........I usually edc two lights on one made for indoors that has a big spot and one used when im out....

As I've mentioned before THrunite has a good XP-G R5 drop-in but when Solarforce comes out with one it will probably be a little cheaper...hopefully.

A simple snap-on diffuser would be nice for almost any flashlight but they're hard to come by in general and I don't know why.

I just got done chatting with Jason over at SB and they will be getting Diffusor lenses.....thats at least something. Should be here this coming tuesday.....its not a snap on lense to say the least but it would do for now i guess. And it seems to do a good job at outputting a lot of light. Im going in on one......if i ever get another dropin for my other L2m then im going to put this sucker in there.

It's a step in the right direction. I'm really being to like Shiningbeam. I didn't get what all the fuss was about at first when I saw favorable posts. I'm not that into Romisens although I have one...not too exciting. I saw the SB carried a few things that DX did.

But when I decided to order forward clickies last Sunday and after I put my order in online I got an email from Bryan saying that my order was packed already (on Sunday) and would ship first thing Monday morning. He's on the east coast, I'm on the wst coast but I received them in the mail on Thursday.

Shipping is only $2.75 so it's easier to put in an order even if you don't need anything big at the moment because the shipping isn't going to kill you.

I ended up ordering 4 switches just in case I screwed up one and just in case I wanted them for other lights. The entire order was less than $10.

I'm going to check the accessories area of their website a little more often now.

I have a couple of really nice diffusion filters that came with a dive light (UK Light Cannon) that I sold recently but I kept the filters. I could cut them to fit my two P60 hosts as they work really well but I'd still rather have a quick snap on.

Hey Bryan. Solarforce already has XPG dropins http://www.sbflashlights.com/Solarforce-Dropins/Solarforce-Cree-XPG-Dropin-1-Mode-p58.html

The Thrunite 1.5A, 493 lumen dropins are not bad either http://www.sbflashlights.com/Thrunite-Dropins-c18/

Thanks for joining man....was hoping you would. Can you give us an estimate on how much the lenses are going for, since you have taken most of my monies anyway lol.

I keep eyeing that dropin from the first link.....gotta wait til payday though and not tell the wife. lol

Hey Jake25, welcome aboard, enjoy your stay!

it will be $6.99 shipped (or very close to around there)

@SB Thanks for the warm welcome!

Not bad at all man.......look forward to my order.

Aloha and welcome Jake!

I'm going to call your house while you're at work and let her know what you're up to. Surprised

You dont have too lol...she keeps an eye out on the monies....lmao.

LOL I know she does.......just joking buddy. Wink

Another issue i have noticed is the heat issue......i noticed that the dropin doesnt sit up against the wall as it should and it creates a small heat pocket causing the Head of the light to heat up. I did what Don and Ted did by wrapping the dropin with aluminum tin, i used a redbull can. Cant say how much i used i just made sure that the gap was filled for better heat transfer......Now the light is warm to the touch which is good for a longer lasting led.

I usually just smear some thermal paste on the sides of the drop-in and it seems to work.

Well i plan on getting more...would like an MCE and soon an XPG and would not like to have to clean it all up.

This probably works better on the more recent throat designs with the reflector supported - the older designs like the WF-502 have very little contact with the body of the light and need quite a lot of packing. If I were being careful I'd use a little thermal goop between the layers too. But that gets really messy.If you look at pictures of the Malkoff ones (But I don't spend that much on whole lights (well apart from two of them)) they have a parallel barrel that is much closer to the throat and will make far better thermal contact.

Personally i don't reccomend thermal goop because perfect goop + thin (household) aluminum foil heatsinking on p60 dropins is very hard to do you might get alot of air pockets (if applying goop to each layer) and it gets often very messy. Carefully wrapping with foil is often more than adequate but don't do a half ass job. Thermal goop would be best if you manage to find the exact aluminum or cooper tube to fit in between the host and dropin but thats wishfull thinking. The best would be very thin copper adhesive tape with very little adhesive that doesen't disrupt themals much but i was unable to find it.

Also i believe that star to pill contact on many flashlights needs to improve considerably. At stock form they are often poorly sinked. That silicone glue is often a poor heat conductor in the way they usually use it to glue stars on pill. The two mating surfaces are often far from being flat either. I believe this is oen of the reasons too that a same flashlight model behaves thermally differently between samples if pulling same amps and foil wrapped.

Another approach would be to thermal glue an aluminum/copper ring to the body so dropins may snug fit and can be rplaced easily. But then again i have very little confidence in heat conductivity of thermal epoxy glues.

If someone have acess to a lathe that would be the best option to DIY a dropin tube that fits the difference between hosts. Quite impratical since many p60 hosts does not feture german garade precision machinig... at least my hosts are all quite different regarding inner dropin cavity diameter.

huh?

@gcbryan, not a rant at all, very reasonable concerns and ideas. i hope there will be (cheap) solutions. about the above drop-ins, maybe its just me, but $20-$30 is too much. about shiningbeam, they are great in my experience.

the what are you talking about is directed at the espresso comment. SPAM?
