Simple One hour build - Defiant $5 light, $5 led and a few minutes time.

I bought a couple packages of the Defiant two light specials, from HD. I modded two of them tonight. One with an XM-L T6 and the other with a Nichia 219.

I am showing the Nichia mod.

def1

Here's the package from HD. 2 lights w/batteries, $10.

 

def2

def3

That looks a little like a ledil reflector. It's a plastic reflector & lens. XB-D emitter.

 

 

dfe4

Broken down. 20mm star and ??mm board. It's just a board for the wire contacts, no driver. I will reuse that in this mod.

 

def5

You know, I wonder if I could put the Nichia right on to the XB-D pad. No I can't?? It's too small??

Watch me!

 

 

def6

I've done so many builds, I have run out of copper discs. Now I am down to brass.  I am using two 1/2" discs and two 5/8" discs. Soldered together, they help to give a little heat transfer. Not a lot, but a little.

 

 

dfe5

Pill is ready.

def7

Used the same contact plate. This is an inexpensive mod and it gives you a brighter light to boot.

 

Beam shots are of the stock XB-D and an XM-L. I can tell you that the Nichia has a smaller spot like the XB-D, where the XM-L had a larger spot.

These are all Mouse over shots. Mouse out is the STOCK light. Mouse over is the XM-L light.

 

Stock1

 

stock2

 

sto3

 

Well, there you go. A quick and cheap mod. I will try to do a couple beam shots of the Nichia, but you know what they say, once you have seen one, you have seen 'em all.

One hour mod? I would take a day, and that would be to just do the soldering. Did the mouse over and blow me down, I thought you'd blown a hole through your door and wall. Amazing the difference with the XM-L. Nice mod and super cheap to boot.

That light actually looks quite decently made. Do you have any thoughts on the host other than the hollow pill? Machining, thread and so on?

BTW: TY for sharing this O-L

It is not a driver. Just a contact plate. Just two wires a ground ring and a spring.

very nice mod!

You get a lot of cheap but nice flashlights suitable for modding over there in the states, unlike here in Europe. Lately I found some Varta lights with XRE's in them, might have a go at one of them, but they are just a bit pricy Frown

awesome mod! Thanks for posting this, you inspired me to go through my old inexpensive lights and “pump them up”

I don’t know why I like flashlights so much… I must have been left in the dark for too long as a child! LOL

Old Lumens I’ve been reading your mod posts and wonder how you choose your projects? I’m sure cost is involved but are you looking for metal bodies, battery size, reflector….

I bought the Defiant headlamps at Home Depot and your post made me wonder if they could be modified. Problem I see is that the headlamps are a plastic body which makes a mod less practical.

Good question!

 

Aluminum body first and foremost. After that, I just look it over. Is it appealing at all, does it seem like it would be worth the modded price, which is the original cost plus all the modding costs.

Battery size, for me, means mostly NiMH- AA, AAA, C, or D. Once in a while a Li-ion, if I feel I know it will resell.

Budget is the biggest thing. $10 or less is great $15 is ok, $20 or over? Not for me. Makes the end result way too high priced. Mod a $50 light and you have a $50 light, which someone just found for $30 somewhere else.

Maglites are my main stream because they are good modding lights and the prices for Incan hosts (so far) stay the same most all the time.

Nice Mod, whats the runtime (and current draw) on the lights with 3aaa, and did you use primaries or eneloops?

Hmm. . . I like!  Might have to try a Nichia in one of these.  Gotta stop by Home Depot soon and see if they still got these!

where do you get the discs (brass) and how do you attach the LED (i.e., pill)? Told you I didn’t know anything. BTW, awesome photos and doable build (I hope).

Thank you Old-Lumens, I've always wanted to try something like this but I was never really clear on how to do it. I have no idea if this is going to work or not but I'm going to give it a shot. I just got back from Home Depot with two sets of these lights. I've had to order everything I'm going to need so I guess it's going to be a couple of weeks before everything gets here and I can give it a try. I'm old, blind without my trifocals and my hands shake but I'm determined to try it. I've read a lot of other "how to do it" posts but none as clear and as simple as this one. From the looks of your pictures I'm assuming you also upgraded the wiring, can you tell me what gauge wire you used?

You're never too old to learn something stupid.

No idea. I don't check amps and volts.

Runtime? left on, about an hour, but alkalines burn bright and then drop off fast, leaving lower output that lasts a good while. Alkaline - Duracell.

Discs are from etsy, just search for the size you want. I normally use copper, but I ran out. Search "5/8 copper disc" or 3/4 disc, or whatever size you want.

I use etsy member "bopper" quite a bit.

Discs are soldered together and then adhered to the aluminum pill with AA (Arctic Alumina adhesive). The star is also adhered with AA.

Great mod, once again!

Not to be a Debbie Downer, but can 3xAAA alkalines run this thing reliably?  Isn't that really stressing the cells to the point that they will rupture?  I'm curious how many amps the thing is pulling.  And what about 3xAAA NiMH, will they be driving the XM-L too hard in DD?

XM-L may stress them, but a Nichia will not. On the ones I have checked with a meter, I never saw more than about an amp out of the AAA Alkalines with any led. I have never had one leak, even when leaving the light on till it got dim as hell. It's probably a possibility, but I have just never seen it.

Run 3xAAA NiMHs. They work fine. I'm just making these to sell to "regular people" and they don't want to screw with rechargeables, but prefer throw aways. NiMH will not hurt the leds. With AAA being such a low output, the voltage drops immediately and you're not putting much over 3 volts in the led. With Alkalines, they read higher (about 4v to start) and then they drop off fast. Remember also that I do not mod the battery holders, so there is considerable V/mA loss thru them. I don't mod them on purpose, to have the resistance there as a buffer of sorts.

Picked up two packs (4 lights) at my local H.D. Figure I'll mod all four eventually. Still a good many at my store.

Wow, incredible job Justin! As somebody else said, a quick 10 minute mod for you would turn into a 10 hour ordeal for me. Smile Your craftsmanship is very admirable. Frontpage’d and Sticky’d.
