There is no way that this thing is hitting 1.5km. My guess would be 1.3km.

Can you read Chinese?!

From what I can see I think the big building is 650 meters? Small house 300 meters? Those are the numbers I see in the middle second level diagram.

If that big building is only 650 meters, to me this looks more like 300Kcd/1095m/1200yards,,,,,,if that. I am just guessing that is what those numbers are.

What are your thoughts?

I would say a bit over rated on throw. However my location and eyes don’t need or see illuminate targets that far. It’s got plenty of output in a cone I can use with useful spill.

This light is probably not a record breaker in numbers (no throw monster, no lumen monster), but is just an amazing light that throws exceptionally well, while having a ton of lumens in the spill resulting in a very pleasant flashlight experience.

I convinced myself lol:

INTERESTED!!!

Would you agree that the big building is suppose to be 650m? If that is the case, in my opinion it is more than a bit over rated. My modded M2X is 250Kcd. It would have a more intense center beam on that building than this light.

Everything is speculation and opinion until you or any of these other guys have one in hand to measure. By what I see I would be shocked if it was more than 350Kcd/1183m/1300yards.

Definitely can’t read Chinese. Lol. An 85mm head with four of these LEDs just won’t do 560kcd. Also someone in the other thread said the intensity is 90% of the X65 mini which is rated 492000. This means it should be 443000. I’ve also read that the meter he was using which is a UT383 is more sensitive to cooler light so it might be a bit less than that. I think it’ll probably be 1.35km at max. I hope I’m wrong but I just can’t see it hitting the claimed 1.5km.

I blew up and thoroughly examined the beam shots of the NI40 SBT90 G2 which I am getting and the Haiklite HT70 SST70.

The NI40 SBT90 G2[advertised at 220Kcd/938m/1025yds.] puts just as much beam intensity[not overall light] on that building which is equal to the HT70.

My final guess when someone gets and measures the HT70 is that it will be between 280Kcd[1058m/1157yds.] and 350Kcd[1183m/1300yds.]

I will not argue that this a a great price for the light.

I can definitely see it doing 350k. If it can do 400k and 12k lumens I’ll be pretty impressed.

Does everyone understand that the battery tube is 2S4P? These are 6v leds so you can run 2 cells in series, 4 cells in series, 6 cells in series or 8 cells in series. The more cells you use the less load on each cell.

It does not use a battery carrier so you have to use button top cells. Kind of like the Q8 battery design, just twice as long.

We don’t know what driver it has but looking at the video above, we can see that it ramps up too High and then a double click to Turbo. This is reminiscent of NarsilM. There’s a good chance they simply adapted the MT09R driver over to this light since they already have it made and it can handle that much power. I don’t know for sure though, they could have always built a new driver from scratch in order to save money.

I checked with Texas_Ace and he confirmed that he had no involvement in this light.

As I write this it seems this light was removed from the Taobao website.

I’ll post a SST-70 output graph from Djozz

If the claimed output is 17000 lumen that equates to 4250 lumen each. According to Djozzs test the leds barely put out 4400 and that is without any optical losses.

In a flashlight where you can expect a 25%-30% loss, let’s be generous and say 25%, you get 3,300 lumen each. Times 4 would be 13,200 lumen and this is using a FET driver. So they are definitely over rating the output.

This would also be a case where it’s drawing about 8A@8v, so times 4 is 32A@8v or 256 watts! So assuming you loaded up 8 cells, each cell would be putting out 8A on Turbo. I don’t see a reason a high capacity cell wouldn’t work, it may just not give as much output as a high drain cell. If protected cells did fit, it would be borderline if a 7A trip limit would allow for Turbo. If the protected limit is less, like 3A or 5A, Turbo would probably trip the circuit.

Here is a HT70 picture from that same thread.

I’m going to take a guess that Djozz’s test might be closer to real outputs. I’ve got a Pflexpro Cree XP-L V6 that Randy measured at 1352 lumens at 3.8 amps in his integrated sphere. Djozz’s listed that at 1500 on his chart, only about 10% difference. Randy has a professional sphere, Djozz calibrates his from a light source he believes is 550 lumens.

Now whether it’s 17,000 or 13,200 the video shows an impressive amount of output in a hand held light. Head, length, tube girth and weight small enough not to be awkward. My little nit-pick is I’d like to see a wee bit bigger tube using Sanyo NCR20700B 4250mAh 15A for capacity and output with only 20.2mm diameter very close to some fat 18650’s. It’s not an EDC but maybe a walking the dog kind of light.

I don’t know about today, but I looked into Randys setup at PFlexPRO about a year and a half ago and although he has a professional sphere, his is not calibrated with a proper reference source. He sort of guessed to get it calibrated based on many factory lights specs. This is not the way to do it. A lot of folks used this approach in the past and usually ended up with higher results than what we see with a calibrated reference source.

Nowadays Maukka is providing some nice lights to use as a calibration source.

I think Djozz has bought one of those to check his numbers, but he still uses his original reference source in order to maintain consistency with his older tests.

Here is a quote from Djozz’s SST-70 test

Quote:
output is in ‘djozz-lumen’ defined as 1/550 of the output of my Sunwayman D40A on high setting, which I hope is close to the real lumen (recent comparisons show that it is actually between 7 and 11% high), but at least is consistent over all my previous emitter tests done in integrating spheres, so all my output data over the past years can be directly compared.

This may mean his 4450 lumen peak is a bit high and output may be a bit lower. So I think it’s safe to say the HT70 output is going to be under 13,000 lumen when measured by any sphere using a Maukka calibration light.

Haikelite is no stranger to exaggerated lumen specs.

Still, with an emitter about the size of the xhp35-hd, but with way higher output, it should be pretty impressive.

I own a good number of PflexPro lights and their lumen measurements are a good bit higher than what I measure with the Texas Ace lumen tube calibrated with Maukka lights. However, since Djozz owns a Maukka calibration light, I trust his measurements of this emitter to be pretty accurate.

I wonder how this light will look like (tint and throw) if the domes on the emitters were shaved. Wonder if any manufacturer can reliably do this.

I noticed on the first page on the specification table it mentions a 5000k version, is that available?

Thanks!

@FREE ME.

Thanks for the code.

I am sure you are very busy but I can not make a decision until I get an answer about the availability of NW.As I mentioned in post # 27.

I am interested in NW Only. When will that be available and how long is the code good for?

Thanks

These Two Protected cells have about a 20amp cut off. I have Eight of the Protected Panasonic/Sanyo. If they are not too long and If this comes in NW as advertised, then I may find out.

No, those cells have a 10A limit. When in series it’s still 10A. (Wait, are they saying the protection circuit is set for 20A? I remember seeing these cells a little while back but the protection circuit was set at 10 amp. Maybe they recently upgraded? If so, then 8 of these cells should be able to do 80A before the protection kicks in. Plus these are cheap. I think the 15A Imalents are like $15 each.)

It’s when they are in parallel that you can add up the amperage. So 8 of those would provide 40A 80A. That is plenty for this light.

Do keep in mind that you get the double whammy of extra resistance due to it being a high capacity cell and extra resistance due to the protection circuit.

So 8 high drain, unprotected cells should produce higher output. If your not looking for max output, then those will work fine.

So 8 high drain, unprotected cells should produce higher output. If your not looking for max output, then those will work fine.

Jon's protection circuitry used to be 13A, last I seen for the GA cells - I bought as set of 4 of these way back. These newer style/look GA protected cells have been bumped up apparently. Jon @LionWholesale has one of the best PC designs around, and at a decent price - he even spec's the protection IC and FETs right there in the listing.
