In-depth vid review: Manker Quinlan T01 Compact Thrower (XP-L HI | 1 x AA / 14500)

From the figure but I didn’t see 500 lm for one hour with one Emerlop AA. The figure shows it lasted less than 30 minutes from 500 lm to 200 lm. (The dark purple curve). This is more reasonable by simple math.
Considering the flashlight loss and according to XP-L Hi spec., it probably take 1.5A at 3v. Assume the average voltage of the Enerlop is 1.25v, the time it can last is equal to (1.25*2.5/1.5/3) x efficiency = 0.694 x efficiency (hours). Lasting 0.5 hours corresponds to efficiency of 72%. I think it is pretty good for such 1.2 to 3.x v converter.
Did I missed anything?

@twinclouds - the mfg quote of 1hr is for the non- Constant Current run (the dark purple curve with a step down). I my reply to MK, I missed the "no step down" part of his comment and only focused on the sustained part.

I see. That makes sense to me now. Thanks for your clarification.
Another question I want to ask is: From your experience, how accurate are the Cree’s specs? As discussed previously, it appears to me that XP-L V5 is not as bright as XM-L2 U3, but it was list slightly higher than the latter in the spec. The bin number V5 and U3 are misleading also.

Sorry I've not specifically tested any lights with the two emitters you mentioned (nor am I in the habit of testing bare emitters) but based on the lights I've tested, I'd say they're reasonably accurate (of course take this with grain of salt since I don't have a professional IS but I'm reasonably confident with consistency of my PVC LMD). I think we need to keep in mind that Cree's specs are under optimal conditions (think stable power supply with sufficient heat sinking) and under those scenarios and based on what I've see of the tests some folks have conducted here, I've no reason to doubt the accuracy of their bare emitter claims.

Hello great review, I have a question about the programmable mode.

When your on the programmable side does it remember (memory) the blinky section ?

Can I be in programmed Medium and double click to the Turbo (without step down). And the double click back to Level 2 ???

Chad

Thx Chad and no, it will not memorize any of the blinkies or the CC Turbo mode.

Still sounds like a great little AA light. I was hoping I could jump back and forth without having to cycle other modes.

BG has black and white, both in US warehouse. I cant decide on color……

I think they both look great but as per my feedback to them, it'd be neat if they came out with contrasting color variations like Olight's S1 line. Given most of my lights are Black, I do like this particular raw color.

Would be great if Manker made a AA extension tube for 2 AA’s

Have you tested the current drawn from NiMh AA to produce 500 lm? If the LED takes current of 1.5A at 3v, which is necessary to produce 500lm according to the spec, the current drawn from the AA should be 1.5A*3V/1.25V/efficiency. Assuming efficiency is equal to 0.7, the current will be >5A. Their boost driver must be very powerful and efficient. I am wondering if it is possible to get such a driver anywhere on the market.

@twinclouds - Using the standard leads of my Fluke 289, current was ~2A with Eneloop XX; of course, there can be a bit of resistance like this. It'd likely be higher with thicker wires.

We are all very ill!

lol

Thanks. However, if this is the case, how it can generate 500lm? Unless the current is much higher without the multimeter. Still, in that case I really double it can produce 500 lm.

Gotta keep in mind that ANSI FL1 only calls for max measurement between 30sec and 2 minutes. I don't doubt it achieved 500lms, just not sustained. Based on this standard, even if it only hit 500lms for a fraction of a second and if that's what they achieved from an average of three samples, then that's what they can quote.

I know how we love to bash Chinese lumens but keep in mind SureFire was one of the mfg that helped come up with the ANSI FL1 standard and they don't measure their lights any differently.

As per my Runtime chart, I achieved 493 "lms" measured at 30 seconds on my PVC LMD (however it was still dropping after 30 seconds). It's no integrating sphere of course but I've been pretty happy with the results especially in comparison to other measurements I've seen for this contraption.

Again keep in mind that mfg specs are typically produced under the best conditions (just like the original EPA testing for automobile mpg before it was revised). They also don't provide the ambient temperature or age of the battery (for rechargeable's) which can have a huge impact on this type of testing.

I agree with you that under the best conditions, these specs could be met. So they are not being dishonest but still not telling the whole truth.

Bingo. While the ANSI FL1 was a step in the right direction to help standardize flashlight specs, they are not perfect. IMO, the Runtime Chart is more valuable in helping one determine the true performance of a light. SureFire claimed 400lms for their M3LT (last SF light I tested) and they are generally respected for being honest about their claims but just look at that runtime chart: https://budgetlightforum.com/t/-/6566

Sure it's 400lms but not for a meaningful amount of time.

I feel that all mfg's should start publishing runtime charts for their lights. This would leave no doubt as to the true performance above and beyond the published specs.

I've never really looked at a surefire before. Granted it was 2012, but there's quite a few subpar features on those flashlights with such premium price tags.

I agree with having runtime charts, lots of good info can be obtained from a very simple chart.

Simple question,

What 14500 battery to buy to get the most out of this light?

Post a link if possible. I’m in the USA btw….

Thanks

Updated review to include add’l vid on accessing the hidden Engineering Mode that Manker disclosed in this thread

thanks for that additional video. My light doesn’t have the pre flash. But my light doesn’t also have the one button click to moonlight.
