Flashlight Host and Uncommon Budget Flashlights

Or maybe put it this way, i prefer it to be pushing no more than ~ 1500-2000 lumens for every 100g. That’s for the mass aspect. Not only for the first cold start turbo run, but also subsequent turbo runs from an already warm state coz you have been using the light already and need a turbo, host already at 40 deg C. Heat dissipation via the air is added bonus of coz.

In my case and temperature, 3 mins (most times 2 min 40-50s) is what it gets the 400g BLF Q8 5000lm to 55 deg C thereabouts.

The MS12 may not have a precise stepdown temperature. I might vary from light to light.

I don’t know how accurate a lumen/weight ratio is going to be. There are a lot of variables. Maybe a wattage/surface area would be more accurate.

I did a test, my 700g Trustfire X100 maintained 66 deg C stabily with 30 deg C ambient, 1.43A 16.5 volts from my PSU = 24 watts, light is horizontal orientation so that the fins are vertical and supposed to get some slight convection going. But this 24 input watts means 3.4 watts into each XM-L only, very efficient.

No way that 65 deg C is hand holdable. I tried, 2 seconds is the max I can manage. The youtube reviews, i think it was the Acebeam X45, was doing 165F or 71 deg C before thermal regulation. You’d drop the light nearly instantly if you accidentally tried grabbing it near the head area.
Tailstand-ed, still ok

For sure lumens :mass ratio is going to be a rough guide, hence why i just specified a range (1500-2000 lumens). That’s the easiest to gauge as we have that info easily from the specs and you’d get the answer within a few seconds of eyeballing the numbers. :slight_smile:

Wattage:surface area ratio or mass theorectically makes the most sense, but it also depends on how efficient you think your LEDs are gonna be operating at the driven level, even if we are talking about the same LED type eg XP-L for the Q8 with the output at 3500lm and then at 7000 lm. Varies quite a fair bit, so that’d require a fair bit of work in mapping the lumens to the watt and also the efficiency of the LEDs between NW/CW. Not an impossible task, of course, just more work. You can also measure the wattage of the light, but that requires you to actually get the light first, or hopefully someone already has the figures. But no issue for the popular lights.

For me it such things aren’t super critical to get the exact figures of course, a ballpark figure more than enough suffices when trying to select a light.

Just an XM-L2, but useful for those non-modders who wants a warm white thrower shortie style light.

Oh…this one chinese 7070 emitter light. I was shooting for 268rmb but the seller wanted 318 lowest. Single piece only though.

Someone did a test, conservatively it does 6500 lumens stock and 7.2% drop in lumens at 30s. The Sofirn Q8 comparatively did 6.x % drop at close to 5000 lumens. Not sure if the stock springs/driver would react positively to a spring bypass and electrical contact cleanings, if so 7000-8000 might be possible. Good enough for a 368g light. An olight X7 similar form factor is 9000 lm.

Please refrain from unnecessary bump.

Sorry my bad … actually it’s due to the behavouir of the board.

I edit the last message and it’d be bumped on the first page. It wasnt a delete and repost.

Post #328: I also found this one. They call it the Dongdonghai D8A. It may have a slightly larger reflector than the Astrolux MF02. Nice suggestion to use a XHP70 in it. But I would go for XHP70.2 and direct drive. There are some nice TA 30mm drivers.

Good idea, DD would be savage, if you have the “correct cells” to drive that. Will go chk the associated costs for TA, thx for the idea. :smiley:

The seller has 70.2 in the link i posted so you might save a wee bit on domestic shipping, or just get it from other TB sellers or your fav source.

Look at the flashlight again. The last option is a new one. It seems that is a 2S4P extension tube. Now things are getting really interesting! :sunglasses: The XHP70.2 listed here is the highest P2 bin: https://item.taobao.com/item.htm?id=568795758705

Hmm…….

rmb 248. usd 35. Price is ok.

Nothing too fanciful, more of a thrower than a flooder with the decently large reflector and XP-L HI, so not sure where this 3 x 26650 would be useful (cheap-ass tripod mounted hunting light? :expressionless: ). 3P config though.
Shd be sufficient heatsinking + surface area for constant max level light delivery.

Looks is ok, throwback old school perhaps.
Overall shd pass for a budgetlight thrower just for fun/collection.

I have a couple of Palight years ago, pretty ok stuff.

Same as the PAlight BOSS II, I think.

What are their battery’s like. Most don’t ship decent ones to AUST now.

3 x 26650, 3P config.

Yeah it’s mighty difficult nowadays. Even Taobao 3rd party forwarders with “Sensitive Air” options are trying to ask customers to limit the number of Li-ion cells per consolidated package to around 12 max.

This light is now sold at Banggood as a Haikelite Q30: Haikelite C30 7070LED 12000Lumen 5 Modi Ladeanzeige Licht IPX8 Wasserdicht Sale - Banggood Deutschland-arrival notice-arrival notice

This makes me think a bit less of them as a company. I wonder if people are going to wrongly assume it has Cree emitters and can really do 12,000 lumen?

Maybe this is not a 2018 flashlight, but I saw it yesterday and got intrigued of how good it would be to mod and make it a “nice” push-pull zoomie:

If someone has any input on this, I’d appreciate! :+1:

I have it. I like it, though I have little to compare it to.

Search this forum for “Severe Cold” to read more about it. No, I’m not kidding, “Severe Cold”.
LED is junk, driver is bad but host is OK and it has nice potential.

Ohh, I remember seeing that light! Now I know why it looked so familiar! Thanks for the recall and information Agro! :+1:

I’m considering to buy this light on Alibaba:

The host looks good with all those cooling fins. It is 1S configuration. Does anyone know how you can mod that to 2S and if it is easy to do that?
