Hello All!

I'm very excited to show off a review of a little dropin crafted by Steve Ku, who has named his company Veleno Designs. He had an initial run, but because of problems associated with the driver he obtained, a second run was made with updated drivers.. This review covers the neutral white 2 mode module.

The dropin is meant to be a direct substitute of the Surefire incandescent dropin for E-series lights. It will only fit in the incandescent format of the light.

First off, we'll start with the packaging. Veleno Designs didn't bother to waste money on fancy packaging, and instead opted to make do with what's currently available on the market.
The dropin is actually ingeniously packaged in what appears to be one of those little capsules that used to be common in vending machines which dispence toys..... if only we flashaholics could find such a vending machine which dispensed dropins ;)

Regardless, the dropin is very well packaged and doesn't look like it will be damaged during transit. Mine wasn't.

The dropin itself is made of brass. Ignore the copper on the module for the moment as that is in a different image.

The emitter board appears hand ground, but it is centered well, and soldering looks fine.

the dropin actually included a pretty long strip of copper tape, rather expensive stuff for the record. It appears there is a high variance inside surefire e heads and the tape will make the module fit more snugly for better heat dissipation.

The dropin compared to the stock e2e bulb.

fit's fine! the module also goes inside the battery tube itself

As you can probably tell, I like this module quite a bit! There was only one other tower module for the e series produced, and I believe it was koala's custom towers with a rebel emitter. It's been a while and I feel Ku's dropin is a worthy upgrade to our e series lights.
Pretty short conclusion -- but I'll just flat out say it: Buy it before it's gone! I think I have a new EDC (surefire e2e.. ;) )

these little gems are available ion the veleno designs website:

do visit it!

Oh wow! That is awesome! Will this run on a single primary? I'm gonna look at his site now...Argh it doesn't say if it will run in an E1e with a primary. That would absolutely ROCK if it did!

time to check.. :p I'll go try it now.

edit: unfortunately not.. it works fine on a r123A though!

edit again: refresh veleno's website. I believe he is adding some info now ;)

I just hope the module is robust and built to last. The contacts to the emitter don't look that solid. But I really can't say of course. I hope the 3 mode is available in single cr123 version as well.
 
the emitter seems to be held down well with some sort of heat conducting epoxy.. which will keep the wires stable.

ever look inside a computer chip? those things have crazy thin wires, but the entire chip is held together well, so the wires don't move!

In his sales thread, steve said "current units are shipping with epoxy on the leads". which should make it better.

one issue I can see is if one bumps the led while putting it in the head .. you have to be careful with the led as the design has to be like this.
 
I wonder if I could get it with a lower output on high with the 3 mode. I'd like it to get a solid 90 minutes on high flat regulation.

Are the electronics fully potted? I'm wondering how heat will affect it in a small light like an E1e.
 
These drop-ins are awesome. They provide alot of light and at just 1A they are a perfect balance. I measured the cool tint.

Hows the throw? I'm more of a throw junkie. The pics look ok but there are only about a foot from the wall...

For being in such a small reflector it has some throw, but that is due to the brute lumens comming out of that little module.

It has a noticeable hotspot, but more of a 50% throw 50% flood = IMHO


EDIT: I was comparing this in throw to my super throwers, so it wasn't a fair fight. Yes, this is a throwy little light. Especially considering how small that reflector is.

Most importantly this drop-in fits sooooooo many E-series lights that it is hard to decide where to stuff them in.

How often are these dropins available on his new website. I really want one for my E2D?

Oh wow. I am REALLY interested in a 3-mode when its available for singe primaries...

EDIT: Is it possible to get custom/desired output levels? That would be great.

The first run fit every Surefire and most of the aftermarket E-series bodies I tried. I don't have an E2D, but with an appropriate bezel, it fits on my E2DL body.
