REWIEW OF LUMINTOP SD4A

How do you know that the XM-L2 version of the SD4A is neutral white? I couldn’t find any info on their product page that describes the tint.

Thanks for sharing
Cool looking light this is!

Amazon shows the XM-L2 as Neutral White, and the XP-L HI as Cool White.

That’s true. But from my previous research on the Lumintop SD4A, the Amazon seller “AONIRO J” is the only seller that I’ve found that actually advertises the XM-L2 as neutral white. In fact, I posted a question asking for the tint color temperature, because the color temperature was not previously in the product title. I wanted to make sure that “neutral white” was for real. He replied with 4000-4500K, and changed the title.

AONIRO J is also the only seller I’ve seen so far that sells a neutral white aluminum Lumintop Tool, and the only seller that sells a Nichia 219B aluminum Lumintop Tool, but only on Amazon Japan. It makes me wonder if AONIRO J is selling custom builds of Lumintop flashlights.

I ordered the SD4A and Lumintop Tool from AONIRO J, so I can confirm they really are neutral white. But I asked the question about the XM-L2 tint because no one else advertised the SD4A XM-L2 as neutral white, and I didn’t want the OP’s review to mistakenly claim that ALL SD4A XM-L2s are neutral white unless he was sure.

Thanks for the information. Perhaps you can provide one more piece of info — Lumintop is not real clear on what’s required for the SD4A to take a 18650 or 26650 cell. Is the battery chamber long enough, and all that’s required is an appropriate diameter adapter?

Now the SD4A can’t carry any 18650 or 26650 cell as it is not long enough :person_facepalming: ~

Thank you — guess I’ll stick with my SD10. You might want to change your product page, unless you’re planning to produce a threaded extender (soon).

I bought (still on way) a SD4A because in your official page says:

Now, I will need an adapter for 26650, from you.

@Dan-hilo89,

Many Thanks for all the hard work you put into writing this review.

Nicely done, I liked your User Interface diagrams.

Much appreciated.

Mine was paid for, but my order was eventually cancelled by the seller after a Month or so, as claimed out of stock!

I wish Lumintop were more clear as to if / where we can buy an extension to take longer cells, or whether their website information was a cut & paste mistake from the previous SD10 model description?

Cheers,

Got mine today. My first DOA flashlight.
Not sure what wrong with the light, everything look fine until i switch to SOS mode.

The light never turn on now.
Long RMA process

Which vendor did you buy this light from?
I have this light on my list (keeps growing) but not sure where or who to buy it from.

You can get from ali express Lumintop store or GB.
Myself get from GB from there year end sales

Don’t we need — do you provide? — an extra length battery tube, to fit the longer cells?

I need the adapter for 32600 battery
Mine does not work with D battery. Need an adapter? Does it work with 1.2 / 1.5V batteries?

Very disappointed

Nice looking light ! I wander if they kept the same electronic.., because couple of years ago, I bought 3 of SD10 series for its versatility , good to have in the house something that can run on all types of batteries ! Unfortunately, ALL 3 of them stopped working with type D batteries (1.5 volts) , during an outage...

One is no longer working on any type of batteries , Li-ion or alkaline , and two are working only with the provided bat. holder (4.5 V) , or with Li-ion !

I manage to open the dead one and inside seemed to be an dc-dc convertor and two drivers . I suspect that the dc-dc convertor is for powering the other 2 drivers from 1.5 volts (D cell). Testing it on the bench proved that the dc-dc convertor was no longer working , and the microprocesor for PWM and a capacitor were in short circuit.I can guess that this dc-dc convertor started to work to a higher voltage that leaded to the failure...

I do hope that what happen to mine was just bad luck.., time will tell !

I like Lumintop lights ( I do have 2 hunter T5 that works flawless...) , but SD10 was not the best of their product...

Mine doesn’t work with D cells either. :person_facepalming: Anybody ever figure out why?

My one have both work well with D size battery.
One DOA but after repaired. Everything look fine.

Are you using Alkaline or NiMH?

OK this is weird. I can get a Tenergy Centura NiMH D to work, but a AA Eneloop in an Eneloop D spacer will not work, nor will either Energizer or Rayovac alkaline Ds. It couldn’t be battery length since the Tenergy cells are the shortest out of all four.

Thanks for the review!
