I’m hesitant to say this because i dont want to start a thermal pastegate again but even on my Ti+Cu model only ~half of the MCPCB makes good contact with the shelf (FWIW my Emisar D18 was more or less the same). I added good thermal paste and it seems to transfer heat ok but obviously it could still be better.
I wasn’t used protected cell, just standard length button top NCR18650GA with their 18650 adapter tube. Seems like it is only compatible with flat top 18650. I hope FF will increase the length of the tube slightly to avoid these issues and use the same springs you are using. That would result in the ultimate premium flashlight that should not degrade in performance over time.
It’s all about the flux bin. I’ve measured warmer temps brighter than cooler temps. If both of the lights are the same flux bin (V3), then their brightness should be the same. Though some lux meters seem to be more sensitive to cooler temps so they measure higher output with CW than WW even if the brightness should be the same.
I’m having trouble getting my aux lights to come on. I click 7 times from off and the switch lights change from 2 dots to 4 dots but my blue aux lights don’t come on. I click 7 times again and the switch changes from 4 dots to 2 dots. What am I doing wrong? How do I get my aux lights to come on? They used to work but I turned them off and haven’t used the light in quite in a while. Now I want to turn them back on.
Make sure your battery is charged? It could have drained it enough to allow the button/main LEDs to come on dimly but the aux board has its own low voltage protection so it will stay off.
Good idea, I’ll charge up the battery tonight. The light itself does come on and ramps up and down brightnesses as expected so I didn’t think about the battery since the light worked.
This thought struck me… there is a lot of functionality in the firmware… but yet…there is no mode to turn off leds…
For instance…as a power save mode you could choose to not activate all leds… for instance… you can sacrifice width of the beam in favor of throw. Cause not always you need this wide beam…
Plus it could save a lot power…
E07 is great… but… battery when using high lumen settings… will deplete kind of fast… but its not strange…
All I am saying is if you could turn off leds… to make beam less wide but not sacrifice throw it could bee a good compromise should it would require more physical motion and focus with your hand to focus the beam to the objects…but… to save power it could be worth in in some situations…
Just some ideas for future products… 7 leds is good…but it might not be all scenarios we need to use it… if we only want focus beam with long thru we could give full power turbo to just a few leds… and let the other be off…
An other idea in this mode would be that the firmware would alernate the active leds… when some led turn of some other turn on… the idea would be… as soon as one led get hot a new “cool” led would start and when it get hot it turns of and a new led start… that is cool… it could maybe help thermal performance.
And other idea… is in situation when throw is more important then flood… maybe we could give specific leds extra turbo power which might be possible cause not all 7 leds are running at the same time…
Just some ideas… I like to think outside the box…
With a a firmware complex like this… this kind of functionality is not to far off I think…
E07 is a very good flash light that gives both of best worlds its a flood and throw light in one…
if we could deactivate we could control flood level and maybe even surpass throw with more narrow beam…
The whole idea is to make the flash light even more versatile ofc…
As it is it s already the most balanced and versatile flashlight… ist flood and throw in one… but atleast witht the SST20 the throw could maybe be better…considering the lumen output…
Being able to select any amount of LEDs requires separated channels per LED, which means each channel needs it’s own regulator/FET and enable signal from MCU, or some logic chip to route the signal to the selected channels. As a hobbyist driver designer myself I can only say man, what a nightmare.
