Help Us Build Better Flashlight Spec Pages! What Parameters Actually Matter to You?

LED Flashlights – General Info
1

BLF fam, we need your crash course in flashlight truth-telling :bulb:
When you’re scanning product pages, what specs make or break your decision?

Our current checklist:
• Raw lumens vs sustainable output?
• Battery tech (21700/18650) or runtime graphs?
• IPX ratings vs real-world dunk tests?
• Driver details or keep it simple?
• Throw numbers you actually trust?

Throw us your nitty-gritty specs wishlist – we’re rebuilding our product info system from the ground up. Bonus points if you share examples of specs pages that got it painfully right or hilariously wrong.

No corporate fluff, just real talk for hardcore users. First round of prototypes goes to the most savage feedback! :flashlight::zap:

The more information, the better, in my opinion. Measurements, sustained output, dimensions, CRI, I want it all, including whether it requires flat, button top, unprotected or protected batteries.

Well centered LED

:memo:Okay!

I also think well-centered LED is quite important. Do you think I should use a white wall to demonstrate my well-centered LED effect?

This is more of a fact than an opinion in this case. If I can’t find the information I want, I won’t buy the light and become annoyed at the company for lack of transparency. If someone doesn’t want the info, they can just not read it.

  • Annotated runtime graphs: lumens vs. time and max intensity graphs in candelas (or ANSI range in meters, to compress vertical scale) vs. time. Using proper scales.
  • CCT, CRI/R9, ∆uv for each mode.
  • angular beam intensity distribution plot.
  • exact specs of the LED(a) and optics used.
  • dimensional sketch and total weight

Thank you, mcjtom - this is extremely thorough and very useful for me. I’ll make sure to note them all down. :ok_hand:

Buck driver.
Mechanical switch UI should be programmable (e.g. memory can be on/off),
Electronic switch UI should try to simulate Android UI

bonuses for an engineering drawing/detailed dimensions (not just length, radius, etc.)

Things I look for:
Lots of close up pictures, with at least 1 picture with something recognizable for Scale.
Detailed information about the UI(click on/click off and No Blinky modes in normal cycle)
Information about the emitter and it’s CCT and CRI.

I’d love to see a UltraFire light with Anduril2 maybe the EC1???

Not sure why you’re mentioning another manufacturer’s product in FAQ:

The EC1 is a 18650 light but the specifications say 21700:

The EC1 product page shows it charges via Micro-USB but the package shows it comes with a USB-C cable:

The EC1 product page mentions Osram NM1 with a Maximum Lumen output of 1500 Lumens.
The Osram NM1 isn’t capable of 1500 Lumens:

Got it. Close-up photos and scale reference images for each product are currently being processed.
I’ve noticed many users care deeply about detailed UI info (click on/off and non-blinky modes in normal cycles) — will prioritize that.
Let me check and share details about the EC1 for you.
FAQ issue: Likely caused by unedited AI-generated content. My apologies — this has now been corrected.
EC1 uses an 18650 battery (apologies for the earlier TP1 battery-type mixup).
At full charge, it reaches 1500 lumens.

Thank you so much for checking.
The studio is out of EC1 units right now, but I checked with a colleague and might be able to get one from her. I’ll take photos and videos to show you — just let me know if you need anything else!

And additionally: never ever I have a measurement error of 50 percent (!!!) which could explain this huge difference. Even if I add 20 percent the claimed 1500 lm are way too optimistic for the NM1.

If I remember correctly Simon claimed 900 lumens with a 5A driver.

I need to check with the technical team to confirm whether there was an error in the documentation or if it’s an issue with the LED model. :pleading_face:

This would match perfectly with my results if Simon measured it in a flashlight (loss in reflector and lens)

I’ve taken some photos, and I don’t believe it even reaches 1000 lumens. This is a fact. I will have them remove the false claims and update the information. Thank you both for your help

Do you believe that or have you really measured it?
