Has anybody tried legoing IF25 tube with EC01?

After reading this tread about about month ago I ordered the IF25 because I don’t mod lights and this one looked pretty fascinating to me. I’m not usually bothered much by tint and usually stay in the Cree 3D, SST-20 5000k range when I buy something so I wanted to see what this was like.

But I’m really liking the low end 2700k indoors on the IF25 and since I’m in and out a lot at night it’s really great to be able to use the tint ramp outside to go up to the 6500k range. I’m not noticing much green at all when in the 6500k range. I compared to other SST-20’s I have and this IF25 actually looks about the most white without much yellow or green.

For the price, about $30 delivered, I’m pretty happy with it. UI works well enough for me. The only thing I wish it had was a way to keep the blue switch light on as a locator when the light is turned off. The blue light is only on when the light is on (except moonlight) and used as battery indicator. It will be interesting to see if this tint ramping will become a thing with the Emisar lights.

Your impressions match mine Cyropro.

Very unique feature set.
Fairly well done UI with both output and tint ramping. Shortcut to moonlight, on-off and turbo.
Excellent choice of emitters
Feels good in-hand.
Excellent price given how unique the features are.

However, it is a bit bigger than I’d like. I’d love it if Emisar came out with a tint-ramping D4v3 with the same emitter setup and using a modified version of Anduril with the same controls as the IF25 for tint ramping (click + click-hold). And with the option to blast all 4 LEDs at max power.

Clip from YooToo SD1 is not great but it fits well.

Yes I want D4 with tint ramping but it would D18 with E21A (2000k + 6500k) tint ramping as an accessory.

I bought another one for another mod, this time before pulling out the LEDs I did some measurements.

(Edit : turbo is level 6 not 5)

It does get a bit rosy on turbo, but on the lower levels it’s quite green, especially on the cool white side.

Color rendering on level 4 (high), approximately in the middle of the tint ramp :

Thank you very much for the test, the freeman. I sold my IF25 because it was terribly green at high CCTs and at that time I still didn’t know how reflow an led. Please post the measurements if you swap for other leds

The previous one I put sliced LH351D in it (I posted it in the mod today thread)

In the next one I will try to put E21A in it, 2000-4500K

Blggg · 2020-11-20T21:15:52.000Z

Thank you very much.

After I learnt how to reflow leds, I had a thought of getting LH351D for popping in IF25, but staff from Sofirn told me that the dome of LH351D is too big for the optic.

The sliced leds must have work great. Tints are so rosy. This is probably going to be one of my favourite light.

Firelight2 · 2020-11-20T22:00:58.000Z

I love the tint ramping in the IF25. Great light!

However, the light is too big for me for EDC. I wish I could remove the driver and put it in an Emisar D4. Unfortunately, it’s too wide.

thefreeman · 2020-11-20T22:22:29.000Z

Too thick too, it’s a double PCB :

I also wish for a smaller tint ramping driver.

Has anyone tried swapping SST20 for domed LH351D? I’ve been thinking of popping in the 5700k and 2700k but still doubt if the led really won’t fit the optic as I was told.

The LH351D dome fits but there is barely any play, in practice since the four LEDs wont be perfectly placed I doubt it will fit. Maybe if the LEDs could be perfectly placed by reflowing with the optics on them, but will it survive the heat ?

I swapped some LH351D 5000k 90cri into my IF25A successfully. I haven’t noticed any issues with turbo or otherwise.

OH, that’s nice. How is the beam? Nice, even, floody?

Nice! Do you have any tips for reflowing a multi-emitter board like this?
I’m thinking I only want to swap out only the CW SST-20s in my IF25 for LH351Ds…though I feel like mixing beam patterns may not look so good.

Please tell me how to switch between mode 1 and mode 2 (ramp).
In the manual it says that from on (on) quadruple click.

but this way I don’t change modes.

Thank you very much.

I had the same question. I clicked 4 times from on and the light flickers as if something had registered, but it was still stuck in step mode. I couldn’t figure out how to get it to switch to ramped brightness mode. I tried it about 20 times and eventually it went into ramp brightness group. Seems like the timing is VERY VERY picky! I think what I was seeing was the strobe mode flicker on click 3 and then on the 4th click it turned off strobe mode. I’m still not sure how to get it to change between the stepped and ramping brightness groups. The tint control works as advertised (click then hold to change tint) without any gotchas. Does anybody who has one have any guidance on how to change groups reliably? How fast should those 4 click be to get it to switch between groups vs going into strobe on the 3rd click? I’m afraid to try it again since it was so hard to get it into ramping brightness in the first place. Hopefully I won’t accidentally change it back to stepped brightness mode until I learn the trick.

Not sure why the heck you would design a UI with 3 clicks to strobe but 4 clicks to change ramping groups. Seems like the average user would stumble in the same trap as me of going into strobe with click 3 and click 4 just turns strobe off (instead of 4 clicks switching between groups as intended).

Thanks in advance for any help!

I ran into the same difficulties with the IF25 - the first times I tried to do an electronic lockout or switch modes, I triggered the strobe and then turned it off.
Based on experimentation, it seems that a double-click can be fairly slow, a triple-click needs to be faster, and a quadruple-click needs to be very, very fast.
You seem to get the same window of time (starting from the first click) to make all the clicks - so the more clicks you need, the faster you have to be.

This definitely differs from Anduril, which I feel resets the window of time with each additional click - letting you chain clicks together even if they aren’t lightning-fast.

jimahi · 2020-11-25T06:48:25.000Z

Thanks!

Those 4 clicks were about as fast as I could go with my fingers. It will suck if this goes back into stepped mode. It will take me another hour to get it back to ramping

I’ve never once had a problem myself but I’m used to multi click combos
