I would really love to buy this light but there is something about the UI that doesn’t make sense. I understand the instant strobe in the tactical mode but in the daily mode instead of instant strobe you instant SOS.Who uses that? Is there no instant turbo from off? Will double clicking the main switch from off take it to turbo? No where in the description of the UI does it say so.

3

The Acebeam UI tends to be a bit strange however, their lights are ridiculously well made.

4

the design is amazing looking, too bad no tail stand but thats ok considering how many other lights i have. i bought both p17 and p18, these will be great to keep in the truck or for a walk. i might even carry one for work.

5

I wonder what 4 SFT40 could accomplish that an SBT90.2 couldn’t?

6

i think per watt , the sft 40 shoots longer because of its smaller diode size. also, 4 sft 40 are still cheaper than one sbt90 which i dont mind. i also prefer a 70.3 hi to SBT90, which they use in the new p17. i had to get both.

7

SFT40 does throw further per watt, but not when you have 4 of them in smaller wells compared to 1 sbt90.2 in a much larger reflector. I’m not sure how efficiency of 4 SFT40s compare to 1 sbt90.2, but the SBT90.2 is very efficient at lower outputs (2000 lumens and under).

Cost is definitely a win for the 4 SFT40s I imagine over the 1 SBT90.2 . Maybe that’s what they were going for in this light.

8

Nice analysis! I am still on the fence for P18. 5000lm to 1300lm in 60s is too fast and too lower for $100 light.

9

That is the problem with manufactures being able to claim such high numbers, it shouldn’t be allowed. I for one know the general rule of thumb is a single cell light this size is going to be 700-1500 lumens sustained output. that is more light for any task. Unless you are on a search mission. If you need any more output than that you need to look into multi cell lights, and even most cannot sustain 5000 lumens more than a few minutes. HID will but limited runtimes. So, no matter the emitter, if it is one cell, it will always fall to that range.

10

What couldn’t the SBT90.2 accomplish?

11

What should not be allowed? Typically, days after a light is introduced someone on BLF does a review or a tear down and reveals the true numbers.

Manufacturers really have no opportunity to lie. It all comes out.

12

No, my question is what do 4x SFT40 do better than 1 SBT90.2 in a light this size. I only see lower cost as a win.

13

This- “It has a wide beam pattern for massive coverage.” from AB product description. Four SFT40 would for sure do a better job of massive wide beam coverage than one 90.2

14

Don’t you guys think only 5000 lm max from four of SFT40 is kinda underpowered?
Granted the light can only carry one battery, but still… 1250 lm per SFT40… Why not 1500 or 1750?

15

You could just as easily make a wider beam with the SBT90.2 by either using an OP reflector or a smaller reflector, making for a smaller light. Thermal capacity would take a small hit, but it’s not like that matters much, because as it is, the light is already throttling down from 5000 lumens to 1300 lumens in only 1 minute. Not to mention it’ll be a prettier beam too, as multi-well reflectors make for artifacts in the beam.

16

Why you might choose 3x/4x SFT-40’s vs 1x SBT-90:

Tint: I’ve had and used a LOT of SBT-90 lights, only 1 hasn’t been extremely green at low levels, and many are green even on turbo. Some SFT-40’s can be similarly green on low levels, but good bins (like the one acebeam uses) are quite clean on all levels. Cooler white (6500k vs 5700k), but I’d take clean cool white over warmer but very green.

Efficiency/performance: 4x LEDs will generally be more efficient than 1x LED at low-medium levels. The SFT-40’s also aren’t being driven too hard in this light - accounting for optic losses, it’s only ~3.5-4A per LED, so ~14-16A on turbo, vs ~20A+ to drive an SBT-90 to 5000 lumens.

Regulation/driver: The only fully-regulated SBT-90 lights I know of are multi-cell. As with most Acebeam lights, this likely has a good (buck/boost+FET?) driver that can achieve high brightness even when the battery is low. Not sure about turbo, but at least the 2200lm high should be doable on a low battery. It is weird that Acebeam states the 2200lm high will step down all the way to 100 lumens though. The L35 could sustain 1800 lumens flat.

Beam size/style: With a 50.8mm bezel like the P18 has, a single SBT-90 will produce a relatively tight hotspot, and while the spill will be bright, the brightness difference between spill and hotspot will make it more of a thrower-type beam (it’ll also throw ~850-900m). 4x SFT-40’s will make a larger hotspot and brighter spill, with less (629m according to acebeam) but still very good throw. I think acebeam was going for a more all-round tactical-style light with a hybrid flood/throw beam, and thinking about it that way (along with the other factors), I can see why they went with 4x SFT-40’s over 1x SBT-90.

I think this is meant more as the successor to the Acebeam L35, which uses an XHP70.2 to create a “floody thrower” tactical-style light, so I think it’s maybe a bit more relevant to compare 4x SFT-40’s to 1x XHP70.2. The L35 is 5000 lumens and 490m throw, with a 55mm bezel. This P18 is 5000 lumens and 629m throw with a ~5mm smaller bezel. So performance and size-wise it’s a good upgrade while filling the same role.

I much prefer the UI on the L35 though (and the 5000k XHP70.2 tint), it’s one of, if not the best tactical-style UI’s out there IMO. It would be awesome if Acebeam used the same/similar UI as that but with the dual-tail switch layout of the new P16/17/18. I have the P16 and while the UI is good (I like that you can set the e-switch to low instead of strobe), the older UI on the L35/L18/L19/EC35 is far better and more versatile.

17

I own two flashlights with the 90.2 and would NEVER buy this LED unless it was in a designated thrower because of the Incredible Hulk color tint it makes…

So I have this new P18 ordered and am excited for its arrival…

18

it sucks you got two bottom bin SBTs. Mine is a perfect 5700k no tint shift unless in turbo, it goes to 6500k. compared to some 80 and higher cri leds i own, it fairs sinilar to the 80 ones. i absolutely love it, but it is too demanding for single cell lights. Mine is a MT90 V2.

19

Has anyone’s order shipped? Mine is stuck in processing, maybe this light wasnt ready for release but they needed something new to offer for the holiday…approaching two weeks since ordering

20

Mine shipped this morning (UK time).

The wait was annoying because I assumed that when they announced the ‘on sale’ date I thought they would have stock then. A bit poor really.

I did suggest to Acebeam that they provide information on when an item will be ready to ship to customers.

I am only impatient because I am so keen to receive mine, ideally before Christmas.

I also ordered a copper AA Poketlit but that hasn’t shipped as yet.
