36 LED dropin for 2-6 cell Mags

This one is discussed at great length at the Other Place here. Looked interesting for $23 from eBay. It came in less than a week by tracked airmail - obviously they don't use the slow but very cheap HK Post Bulk mail service. I usually expect 2-3 weeks to here from HK.

 

Anyway, some pictures.

In a Mag I happened to have lying around - it's a 3D with 3 8000mAh LSD Ds in it. The front is quite neat looking.

In head

 

Sitting on the desk. This one shows the bond wires quite clearly.

Side view - it still appears pretty well put together.

still naked

 

It has 36 Nichia GS LEDs in it and has the typical colour of those - a purplish hotspot surrounded by a sunny yellow spill with a rather green corona. Here it is about a foot from the ceiling. Obviously the hotspot is grossly overexposed.

Beam indoors

 

Looks dark enough for beamshots but there are nesting seagulls on my roof and one of their chicks has made it to ground level (doesn't have flight feathers yet so I'm hoping the neighbourhood cats see it off soon) and they are very aggressively defending it - there is seagull crap everywhere. To add to the fun, they are a protected species here so I can't do anything about the rats with wings. Don't fancy getting the camera crapped on so outdoors beamshots will have to wait.

 

Current draw with 3 Ds is 1125mA, with 4 it is 1055mA and with 2 it is around 1100mA. These figures will be subject to revision once I've charged up the cells and done the meter stuff etc. This is with cells that have been running it for at least 4 hours now.

 

The numbers from my light tests are always to be found here.

Throw: 2620 lux at one metre - this is a flood light, not a thrower

Lightbox: 1392 lux which puts it over 300 lumens. These figures were with three NiMH D cells so current delivery is not a problem here. This configuration should be good for 7 hours with the 8000mAh cells in it.

 

Dug out some 3AA-D adaptors and tried it in a 2D with 6 eneloops totalling 8.3V behind it. This gives a current draw of 875mA and 2030 lux on the lightbox. This configuration ought to be good for two or so hours and is roughly 400-450 lumens.

 

With a 6D war club it'd give about 9hrs of a lot of light.

Hey Don,

 

Thanks for posting about this.

I’ve been toying with the idea buying a big Maglite to mod for a while but have been waiting to find them on sale and just noticed 7dayshop.co.uk  are selling them.

Seem to be cheaper than other places but I’m not sure of the going rate, do the prices look any good to you?

 

Cheers,

Gary

It is often worth looking around in electrical stores and B&Q who are often clearing out Mags. I got a pair of 2Ds for £7 each from the Currys across the road from where I work. The 7dayshop website is down just now so I can't check their prices but they are usually OK.

I got two 6Ds (These are way too big to be useful) from B&Q for less than 25 quid for the pair of them when they were clearing out Maglites. Actually the new LED ones with the Rebel LED are pretty decent though way overpriced here and not very practical for modding. 

 

Now that the 7dayshop website is back, the prices look tolerable, but it is probably worth looking round your local High Street shops. Lots of places have a few Maglites knocking around - mostly at crazy prices but sometimes quite cheap.

7dayshop is probably as good a price as you will get unless you can find them on offer somewhere

4 hours

1123 lux / 250 lumens The same as an hour ago.

80% after 4 hours is pretty good - especially when it is over 200 lumens.

Cheers for this Don.      

 

200 lumens after 4 hours is impressive stuff! these showerhead dropins are the badgers nadgers, i have one in a 6D mag beside the bed for those woken at 3am by an elbow in the ribs "i heard a noise downstairs/out front/in the garden" moments and another will replace the ROP low in my 2C mag when it blows, unbeatable bang for the buck.

Now down to 1112 lux / 247 lumens Down to 79%. 

 

Unless it drops like a stone soon I think it might do over 7 hours.

 

Once I've let the cells recover and charged them, I'll try it in a 6D with 6 NiCd(5,000mAh) and 6 NiMH (8,000mAh) cells

7 hours 23 minutes to 50%. Stopping the run at 7:30 just to be kinder to the cells. At 7:29 output stopped. Dropin warm but not hot.

 

Then time for beamshots with 6 NiCd D cells I happen to have freshly charged.

 

Outputs

Switch-on     1937 lux / 430 lumens

30 seconds  1868 lux / 415 lumens

2 minutes     1790 lux / 398 lumens

The usual tree - shorter exposure than usual - just realised when I looked at the EXIF data.

3D NiMH (8,000mAh)

Around 311 lumens at switch-on

3D

 

6D NiCd (5,000mAh)

Around 400 lumens at switch-on. I'd expect 8hr 30min with the 8,000mAh NiMH Ds.

6D

I have one of those cheap 1 or 2 million candle power floodlights but it is bulky and I don’t like the captive battery setup so with one of these dropins running on 6 NIMHs the Maglite is now, for me, a far more compact and useable flooder.

 

I’m a bit late with this but I have to say a big thank you to Don for selling me a brand new 2D Maglite at the sale price he bought it for.

It was sent extremely quickly (despite the rainLaughing) and was very well packaged.

Thanks again Don, very happy with it and the adapters.

 

I bought 2 of the dropins from the ebay seller so was sent a free 2xAAA penlight which was nice but I must say I’d be very disappointed if I had paid the $6.50 he’s asking for them on their own.

 

Cheers,

Gary

Can you do a little review or a "first impressions" with some beamshot photos with a well known light next to it? I wanna know how a nichia warm looks like. Thanks in advance.

No problem, but it might take a while to arrive (it's a reservation so I don't know when they'll ship it).

I just got mine. I'll update when I get home and use it. I don't have the first batch so can't really compare.

Impressions:

 

1. The "throw" at the center is still bluish, but the flood around it is warmish. The blue isn't that big of a deal when you're actually looking at what the light's pointed at instead of the color.

 

2. The flood is quite wide. It's a nichia keylight chain x 36.

 

3. This makes it very nice indoors, but not great for looking at any distance outdoors.

 

The easy way to think of it is basically a giant UniqueFire AA-S1. A great indoor light.

 

Is it worth $25 + maglite? Obviously you're getting some value with so many nichia's, but it's not really a general purpose light. However, it's very good at fullfilling its niche. if you're the kind of person to get a thrower just because, you should probably get this. It's the ultimate light in the house.

 

There's only two good ways to configure this light. A 2D mag with 2 3xAA adapters for ultimate brightness (I like it bright), or 3D for runtime, or I guess a 2D in either config if you only get one host. The output scales linearly above 3 batteries.

My 3 d mag works great with the drop in and two 18650's with a dummy battery. They will take up to 9 volt safely. (I tried it with 12 v for a short period)

Hi kevinvalid

welcome to BLF you will have no problems running it from 2-9v it seems at its happiest around 7-8v the one i killed was all in the name of science

 it is the most light you will get for your money in a Mag-lite upgrade and as easy as changing the bulb

Thanks for posting this.  I dunno how I haven't seen this before... My parents love the color Green, so for Xmas I'm going to get them this drop-in and install it into a 3D Jade Mag for them.  Should be a great present for them assuming i get all the pieces in time LoL!

When I first got this dropin I was pretty enthused about it .

I bought several for my buddies and all of them are still operational over a year later .

I'm really enthused about it and it's a gift!  Now I'm sorry I didn't order more of them for MEEEEEEEEEEEEEEEEEEEEEEEEE!
