Even if one of the mirrors in a LEP-module is damaged, or in case of the back-illuminated version the phosfor disc is damaged/removed, the lasers are not parallel but are focused at short distance, namely on the phosfor, so the light will always leave the device as a highly divergent beam which is hardly harmful. The danger of laser pointers and such is the parallel beam that keeps the light highly concentrated at all distances.
That is possible but there are a huge number of other useful tools that can cause worse injuries if used improperly. I use wraparound safety glasses if I’m going to safely start a campfire or something. Some of my lasers were $20 or less although I have a few that were hundreds of dollars
Also fun for wood burning. I made a gift for my wife one year by burning her name into a piece of wood I found.
This explains the low throw but doesn’t explain the low Lumens does it? Does the light not filling a large portion of the optic mean some of it is blocked from existing the light, resulting in the low lumen count? I see why filling only a portion of the optic decreases throw, but I don’t understand why that would decrease the lumens.
I’m ready to get my first LEP light but in doing some research I found a very interesting comparison site that showed candela values that were monstrously different from BLF sources I checked.
Furthermore, the part that scared me is: within the interactive candela graph at the bottom of the page, it shows the Astrolux WP2 losing 59% of it’s initial candela after only 2m:45s which is extremely drastic considering that this was the front runner in my current purchase decision.
Results from chart WP2
initial - 1278kcd
drop after - 2:45 500kcd
final sustained candela after 14:00 - 388kcd
IIRRC I’ve seen lumen output charts putting the WP2 sustained at almost 2 hours but this is the first candela chart I’ve seen.
Does anyone have any insight?
Also: anyone have experience with this site to confirm if his results are trustable?
That site appears to be either associated with chibim… or stealing his graphs. Maybe he can tell us which. My guess is they’re stealing his work to try to get paid for referrals.
Well I guess I was wrong then. I couldn’t find any info linking it to him. I tend to be overly suspicious sometimes. I mean, after all we do have an entire thread of people ripping off Matt Smith’s videos to sell every knock off flashlight in the book…
For the W4, I see Neal carries it so I would FB message and/or email Neal to ask him what's the best deal he can give me, saying I'm on BLF. It's worked for me every time (few times).
That’s a good call! Neal is well informed as to who I am. lol my wallet doesn’t think that’s anywhere near as funny as I do!
In fact I decided to punish my wallet even more today and pulled the trigger on the Xsword - Chibim has a code up that lasts until April 30th. lol one of those had to do it moments is how I sleep at night
Anybody with any knowledge of designs in the pipeline? I’d love to see a 2*21350 33mm head diameter light from Maxtoch for example. W10gii intensity but sustainable for the full battery discharge. Imagine a sustained 600kcd in a P60 sized light. I’d sell 2/3rds the throwers I have for this.
You just need the right driver. The buck/boost IC used in the Lume1 for example is more than enough to keep a lep module powered at full brightness, even off an 18350 for a good 15 minutes. Heat is an issue as laser diodes are very sensitive.
Yes, a boost driver would do as well. 2S buck seems more common in the wild than 1S boost for 4-5V out though which is why I mentioned that.
I don’t actually care if they run continuously at full brightness, but rather at any given SOC, it’ll turn on and deliver full output. I hate having to keep cells at 4+ volts to achieve peak output, especially in low use lights that degrade these pricy and now hard to get cells.
