Review: Lumintop SD10 1D/3x AA/32650/26650/18650 "Household Searchlight"

Lumintop SD10 "Household Searchlight" Review

Reviewer's Overall Rating:  ★★★★★

 

Summary:

Battery: 3x AA, 1x D, 1x 18650/26650/32650
Switch: Electronic side switch
Modes: L/M/H with memory, hidden strobe (double click)
LED Type: XM-L2 T6 Cool white
Lens: AR coated lens
Tailstands: Yes
Price Paid: $53
From:hkequipment
Date Ordered: 7/12/13 (received 7/31/13)

 

Pros:

  • Runs on basically any battery config you could imagine
  • Low mode is in fact low enough
  • Easy lockout prevents parasitic drain (loosen tail cap 1/4 turn)
  • Good build quality (except battery carrier)

Cons:

  • Might be a tad on the expensive side for some.
  • Might be difficult to mod?? - more on this later
  • No reverse polarity protection
  • Battery carrier is cheap and not well built.

Manufacturer specs:

SD10 is one of the world’s smallest, lightest and brightest 32650 searchlight. It is compatible with a wide range of batteries through intelligent control, and thus it has different outputs based on different battery types. It ensures not only enough brightness but also product stability and long runtime. With premium CREE XM-L2 T6 LED, its output reaches up to 800 lumens.

 

 

 

Construction:
1. Coated tempered window resists impact.
2. Aerospace aluminum uni-body design combined with a stainless steel retaining ring offers superior impact resistance. Mil-Spec hard-anodized. O-ring Sealed.
3. Front side switch.
4. Superb heat release system provides excellent heat transport capacity.
5. Slip-resistant body design.
6. Lengthened lanyard hole with tail-standing design.

 

 

 

Operation:
A. OFF State:
Press and hold the front side switch for more than 0.5 seconds to turn on the light, while another press for 0.5 seconds will turn the light off.
B. ON State:
Click the front side switch to switch between 3 output modes: High, Medium and Low. Double click the switch to enter into Strobe mode, after another click, the light will go back to original brightness. It memorizes last brightness level when the light is turned off, while Strobe will not be memorized.

 

 

 

Note:Putting the SD10 battery carrier into the body reversely may cause a breakdown in the circuit.

 

Length

4.69 inches (120.3mm)

Diameter

1.56 inches (40mm)

Weight

4.03 ounces (115g)

 

 

 

 

 

Features / Value:  ★★★★★

Light arrived sealed in a bubble envelope in a nice box with extra o-ring and a lanyard.

 

This light runs on any batteries pictured below!

 

The light will run on any of the following batteries: 1x 18650 (with a 26650 spacer), 1x 26650 (protected might not work depending on cell length), 1x 32650 (feilong unprotected), 3x AA (nimh or alkaline), and 1x D size alkaline.

I did try to fit a C size battery, but the cell is too short to make contact on the negative spring and would need a spacer.

I did not try 3x AA lithium as I do not have any on hand.

 

Design / Build Quality: ★★★★

Threads are square and do not wobble.

Switch is a little on the "squishy" side, but works fine and glows a nice green when you press down on it. It would have been nice if this switch always glowed green when batteries were inserted. (like the terminator). Switch is electronic and can easily be locked out by loosening the tail cap a quarter turn.

Knurling is adequate and provides sufficient grip.

Emitter is well centered and the lens is AR coated Smile - note I believe the bezel can be unscrewed and removed to access the emitter. I do not have a way to open the bezel without fear of scratching it, but I suspect you modders could access the emitter through the bezel. The reflector is shallow enough where I believe it wouldn't be too hard to swap the emitter through the front of the light.

Other thoughts:

The reason for the 4 star rating is the battery carrier. Frankly - its a piece of crap. It does get the job done, but it made of plastic and has puny springs. It will wobble around in the light as well since the battery compartment of the light is larger than the carrier itself. I would have liked to see something along the lines of the battery carrier the Xintd x3 uses - especially since this is a $53 light.

Battery Life: Not reviewed.

I have not done extensive runtime testing with batteries yet. Here are the manufacturer specs though.

Battery type

1×32650

3×AA

1×D

Low output / runtime

10lm / 280h

10lm / 150h

2lm / 60days

Medium output/ runtime

100lm / 26h

100lm / 15h

30lm / 80h

High output/ runtime

800lm / 7.5h

500lm / 6h

200lm / 7.2h

 

 

 

 

 

Light Output:  ★★★★★

For its size, the SD10 does quite well. Output on high on any battery config is enough to light up my living room. The low mode on any cell config is also "low enough" for you moonlight mode freaks as well.

Here are some comparative ceiling bounce numbers for reference.

1x D alkaline

L - 0.1 lux

M - 4.5 lux

H - 19.3 lux (18.5 lux @ 30 sec)

3x AA eneloop

L - 0.8 lux

M - 8.8 lux

H - 62.8 lux (59.0 lux @ 30 sec)

1x Li-Ion

L - 0.8 lux

M - 10.2 lux

H - 76 lux (73.8 lux @ 30 sec)

 

Here is a shot on high (I took more photos of the different output levels, but I really do not like the way they came out - I am still figuring out my new camera)

 

One last note - the hot spot of this light is slightly on the "square" side - I believe this is due to the shallow reflector and the XML2's square die shape. This does not bother me at all and does not detract from the light in any way - but I felt it was worth mentioning. I tried measuring current - but I my cheap multimeter/leads are not up to the task. Sorry!

 

Based on the "relative" ceiling bounce numbers and comparison to other lights I feel the manufacturer's lumen claims to be accurate.

 

Summary:  ★★★★★

This is a great light - It will run on basically any type of battery you want and provide a good amount of usable light on any output setting. Tint is cool white & free of any purples/greens etc. The cheap battery carrier can be overlooked as it really has not interfered with the general day to day use of my light. I regularly use 3x eneloops with no issues. Is this light worth $53? To me it is. I have seen this light for sale at wallbuys for $45 during an "instant kill" sale - so it is probably possible that we will see some prices in the high $40s in the future.

Thanks for your review, jmpaul320, well done ;)!

I hope you will be able to provide some tailcap measurements and also see how much the output Amp draw sags over time!

It seems that you love yours, good to know that its a decent light!

Cheapest one Ive seen is 47$ shipped, others sell at well above 50$, probably due to MAP restrictions.

One question – how is the PWM on med/low modes? According to review at CPF it says that it has ugly PWM on low and slightly noticeable on medium?

Also, Ive found out at this russian forum that someone has supposedly replaced its emitter with XP-G2 and that it uses some sort of sticky compound instead of hard one to glue parts together, so at least we know that someone has done successfull emitter swap!

Also, couple of posts lower it is said that Lumintop has confirmed that this light should work with 4*AA and that FT’s 4*AA holder will be used by forum member to try it out. Interesting…

I am sensitive to PWM – I do not notice any dizzying effects or flickering on any mode.

Good to know about the emitter!

And also good to know about the 4AA carrier option – this means the light should work fine on 3 AA lithiums and the driver will accept up to ~6v

Thank you for the nice review! It is especially interesting that it takes d cells and lasts 7 hours at 200 lumens.

its 200 lumens on a fresh d cell

the output will taper over time

I believe ansi specs are runtimes to 5% output

Thank you for the review.
After my experience with Super Storm Sandy, I made sure to purchase 4 of the SD10.
To me the SD10 is a real emergency illumination instrument.
Cosmetic appearance, thousands of lumens and miles of reach is all child play in a real SHTF situation.

Great review, jmpaul 320!I think this is the ultimate bug out bag flashlight with a myriad of power options.The AA battery carrier is really disappointing in the fact that you get these carriers with "cheapo" lights.I'm glad to see that you couldn't notice PWM because it would be a definite deal breaker for me.Thanks for the review and congrats on the new camera,lol.

Here is a carrier you can use with this light running the 3 AA in parellel rather than series, for longer run time:

interesting! so with 3 eneloop you should get about 6 amp hours +/-

thats about half what a D cell is i believe but still another cool option!

Depends on the capacity of the D cell. You could use 3 Turnigy 2400mAh AA

IMO not likely to happen, unless some magical mega-group buy happens, for that price Id buy 2 or 3 :D!

BTW, Wallbuys has it for 59$, not cheap.

Cheapest Ive found, as I said earlier, has been 47$ ;)!

I bought mine from hkequipement.net on 3 Aug 13.

Start using it from 24 Aug13. Use it every day as night light. Using low mode with a silicon diffuser.

Then two days ago (12 Sep 13), it suddenly refuses to turn on. The power switch still give green light when press on.

Tried with 3 x AAA with adaptor, Li-Ion 32850, D Cell and 1 x AA using AA to D Cell adaptor but the SD10 still won’t turn on.

Not even close, not unless there's a firefly mode below it.

The low mode should be lower.

I just got a SD10, the switch makes no click at all, but modes change when switch is pushed. Is it normal for the switch to not click?

Yes, that’s the original version switch that you received. The updated version is the one that makes an audible click.

Correct me if I’m wrong, jmpaul; but couldn’t you run 3 × 14500 cells (3.7v) in parallel and get the full output as in using a single 26650 cell? I noticed full output on 3 x eneloops (in series) only gets you 500 lumens, tops.

Lights out! That's when things get interesting...

you could, but a 26650 or 32650 would provide more runtime

I dont think theres NW version out there, at least mine is definitely WW one ;)!
If search button returned no data regarding NW availability from usual retailers, perhaps contact Lumintop and see if they can help you out with this?

Not even close.  It's too much by 1-3 orders of magnitude.

The low mode should be lower.

I actually intended to post my question there but didn’t check the correct thread… I’ll post it there, too.


Ah, I see, I assumed that admins review is about the same version that I reviewed a while ago, hence why I only paid attention to parts of his review that I was interested in and glided above the explanation about it being Lumintops 2nd attempt at neutral white :D!

Hmm, looks like there are now 3 versions of SD10? I wonder if the one that I reviewed has been released to general public and how many have been sold in general, white vs warm vs neutral?

Good to see that theres now true neutral white available to complement their regular white and warm white versions :D!
