Milky Room Sweeper

[Taboot]

Oh man. I want my E2E to get this mod. Nice work guys.

It'll be impressive for its size...wait till the darn thing heats up

Normally I'd agree with that.... but it's one of Milky's creations. I'm sure he built in something to keep it from going

[Hogokansatsukan]

The head is quite heavy now from the custom brass heat sink Milky put in. I don't see a in it's future.

Can you still use the pocket-carry clip with this light, or does the heavier head cause it to sag away from a pants-pocket if clipped there?

[Crenshaw]

The work Scott did was incredible, and he is an extremely nice guy to talk with and knows his subject matter.
I can definitely see more projects going to Milkyspit. He makes tools we can use.

Hogo.

I've run it for 5-10 minutes continuous with no problems, not even a tint shift from the P7. (A tint shift in the blue direction is a warning sign with Seoul P4 and P7 that the emitter is getting too warm for good operation, and more likely to fail soon.) After the first few minutes the emitter is actually underdriven, making risk of failure lower still. The brass heatsink does a good job of wicking heat away from the emitter, and the speed with which the outside of the head gets warm suggests thermal transfer is working well in this case.

Now that's what I call a flood! The beam pattern looks somewhat similar to a Surefire L4 from what I can see of it, but a lot brighter!

The E2E reflector is tough to beat in terms of how WIDE the spill beam is... made it a natural for this application. As for flood... there IS a hotspot, just a very soft one.

Nice job on the Room Sweeper!

The question I had for Milky, which I bet one of you know anyway, is if anyone has posted beamshots of an L1 Milky modded light vs. a stock L1 Cree?

And to the OP of this thread, is there any chance you could do either an outside beamshot of the Room Sweeper and/or compare it to something well known?

Crenshaw, I still love your Legolas build... the parts to get it done cost a fair bit but what a nice finished product. Eventually I'm probably going to build one for myself, too!

Thanks for the kind words; they're much appreciated.

(Sorry to wander off-topic, Hogo.)

[Crenshaw]

im actually almost jealous that my own milky has *only* has 300+ lumens....

I've got some photos which I'll post in this thread ASAP. Not sure if I have any of the stock L1 Cree, but I do have comparisons with a couple other lights so people at least can get the general idea of how this one might differ from something they already know.

[Crenshaw]

building one for yourself?...wow!...

by the way, ive been accumalating differnt body's for it...i have one of the last Maxalite AA bodys sold at TnC, and i also have a Nitecore Extreme on the way.....ought to be interesting...and AWs are rated up to 2C discharge right? worth a shot...

anyway, sorry for OT...

@wattnot, i think its hard, because once you've gone milky, its unlikley you buy another L1 without the expressed purpose of having it shiped directly to him for work. I did consider getting an L1 for this purpose, but then theres always the question of what to do with it after.What might work, is if someone using a camera on manual, takes a picture with as little ambient light as possible, and a specific arpeture and shutter, i would be up for recreating those conditions with my Legolas...

Room Sweeper Photos

Tried to capture a realistic look at how the Room Sweeper beam compares with a more typical flashlight beam, especially for something somewhat along the lines of the customer's intended purpose. (In truth I probably don't understand the intended application fully, so these are based on my best assumptions at the moment!)

The Light Itself

First, a handful of photos showing the Room Sweeper itself from various vantage points.

Beam Profiles

The beam has a soft hotspot coupled with unusually wide sidespill, these attributes deliberately chosen for maximized coverage of a typical room in a house when illuminated from the room's doorway. At the same time, goal with the hotspot is to deliver enough range to illuminate targets at the far end of the room while not causing significant glare for the user.

Beam Profile #1: Note how beam converges a little distance beyond the head of the light


Beam Profile #2: Note the wide angle of sidespill


Room Sweeper vs. Novatac 120p

Lots of people are familiar with the Novatac 120p, so it was a natural choice in comparison beamshots... its balanced beam also serves as a good representation of a "normal" flashlight's coverage profile, at least IMHO.

The goal isn't to make the Nova120 look bad! Rather, it's to show what a good quality general-purpose flashlight would look like in the same situations for which the Room Sweeper was designed.

The Room Sweeper tends to overwhelm the 120p in sheer output... the difference gets compounded as one moves to the edge of each image, where the 120p leaves shadows that could conceal a bad guy, delaying recognition... the Room Sweeper tends to eliminate the shadows for faster identification.

Room Sweeper vs. Creemator

The Creemator is one of my more popular builds and delivers a significantly brighter beam than the Nova120, with hotspot far more intense than that of the Room Sweeper. Again, the goal is to show how a Creemator would look in the situations for which the Room Sweeper was designed. This particular Creemator has a Cree R2WC emitter for a rated max output of 322 lumens, and has a custom-cut McR19 reflector for more sidespill than the usual build at the cost of somewhat less throw.

In general, note how the Creemator delivers lots more light to the area inside the hotspot, but light intensity falls off far more quickly when moving to the sides... the Room Sweeper has more even coverage of the room. If one knew where the bad guy was hiding, the Creemator might make a great tactical choice... but going into a room blind, so to speak, the Room Sweeper probably allows one to locate the bad guy wherever he is in the room more quickly, without regard to exactly where in the room the hotspot was pointed.

Great beamshots, Scott! Someone asked about getting blinded earlier--if anything, the intense hotspot of a more typical high-output LED, like the Creemator, is probably more likely to blind you with bounce-back from a wall than the Room Sweeper, I would think. Those beamshots make it look like the difference between searching with a flashlight and simply flipping on the room lights.

[climberkid]

brilliant idea to take pictures of room of a house....for the room sweeper. haha pure genius.

[kaichu dento]

After seeing those shots all I could think was that all police agencies and military personnel should be carrying one as required equipment.

[Lookin4U]

So... How small can you make one that'll do that for a couple of hours? I also have to light up rooms, but usually for a lot longer... and after the SWAT guys are finished...

[Hogokansatsukan]

I didn't figure outside beam shots were needed after Milky's great photos. After all, the light is for indoor use. I did get it out in the desert last night, and once again, was completely impressed. The hot spot is much more noticable at distance and it does throw farther than the NT light. This will light up a backyard without any problem, and not just a corner of it!

After that beautiful description, your going to deny a Flashaholic beamshot porn? Shorty and Longman meet the long arm of the law, Milky Room Sweeper!

Beamshots!...beamshots!!...beamshots!!!

I just have not figured out how to get blue funtac to stick to the beams.
Once I get that figured out...

[Flashlight Aficionado]

Stick the blue funtac to the wall or whatever the beam is hitting. Or just photoshop it.

[1203]

No doubt about it, I have to get a Milkyspit mod.

[Illum]

so what does Milky need? just an E head?

[milkyspit]

E head and a body if you have one... ideally I'd like to have the body to make sure the 17670 fits properly, and the module mounted in the head closes properly with the body.

I can probably locate an E2E or similar for you if it comes to that. Could also build in one of the SureFire LED heads, such as KX1 or KX2, and mount a modified version of the Acorn driver to give the thing multi-brightness. Would still run on a single lithium-ion rechargeable.

BTW, my PM is often full lately, plus with CPF possibly out for a few days sometime soon, you might want to get in touch via email...



If going the email, route, please put "CPF" and your username somewhere in the subject line... makes it a LOT easier keeping track of things!

I'm glad and HONORED that Hogo is finding the Room Sweeper so useful. I put a lot of effort into getting it right for his needs, so that means a lot.

[Hogokansatsukan]

It is perfect! Expect a big box of E2E lights by the end of next week for conversion to Room Sweepers! My partner is moving to the Feds this week and I nearly had to wrestle her to the ground to get this one away from her.

[climberkid]

how does the surface area of the E2D compare to the E2E for heatsinking purposes for modification to a room sweeper?

[Illum]

thanks, I asked for the purpose of clairification. For now I don't have that much money to spend...


I want one, can't afford one

[milkyspit]

how does the surface area of the E2D compare to the E2E for heatsinking purposes for modification to a room sweeper?

Climberkid, both heads should work equally well... for all intents and purposes they're the same head other than the crenelations at the top of the E2D head.

[Youfoundnemo]

Milkyspit, minght i ask why you choose a picture of four children at a table as your " signature" or "Trademark"?

[Hogokansatsukan]

OK. I was bad this weekend. I used the light a lot in the field and it works wonderfully in real life use. That isn’t how I was bad.
I went into a local police supply store here. Some of the guys who work there can be a bit egotistical and condescending simply because they retired from xxxx, generally in the Peoples Republic of CA. So, Podunk me strolls into the shop and starts perusing the flashlights. Victim clerk comes up and asks if he can help. I had to time it right as I had a particular clerk in mind. (He’s been there, done that, and single handedly saved the world on several occasions. Oh, and he owns everything in the world, or has owned it and got rid of it because “it wasn’t good enough”.) I say I’m looking for a light but doubt he has anything brighter than what I already carry. Of course he asks what I’m carrying, I pull out the Milky Room Sweeper (E2E) but don’t turn it on. Poor victim laughs and pulls out a few SF and SL lights. I let him demo them showing me the beams, then I say. Nope. They aren’t brighter than this. I shine it on the counter, then say thanks and walk out the store before he has a chance to respond, leaving him totally confused.
I know the next time I go in there for something he will make a bee line straight for me trying to figure out what light I had with me.
