I just realized that the optic used in my latest two E07 is narrower throw than the optic used in the older E07. Comparing my new E07 SST-20 with older E07 SST-20 and comparing my new E07 XP-L HI with older E07 XP-L HI, it is very obvious that the hotspots from the newer E07 are smaller compared to the hotspots of the older batch of E07 using the same emitter. However, I cannot tell a visual difference in the optics.

Ok, so, now that I’ve read this entire thread, I’ve learned a lot. The only thing that I still don’t understand is the debate on a 30T battery vs. 40T. Without getting really technical, which one is the best for the E07?

30T is for lumen testing only. No noticeable output differenc e in reality. 40T and P42A is best for XPL HI and SST20 std cri versions. Lishen LR2170SF best for SST20 hi cri and 219b

I bought a 30T on 18650 battery store for the DEAL OF THE DAY SALE. $3.99 BUT, the 40T was $6.99. Ok, thanks guys.

*SKV89, I’m having a MF01 Mini 4000K SST-20 FD which is going to be modded with the copper heatsink, so it’s also a opportunity to swap the leds.
In the beginning I was opting for the 219B SW40 but someone told me they are too violet under clear narrow tir optics. Besides I’m not thrilled to loose both output and range.

Do you consider swapping the FD2 SST-20’s to FA3 worthy?

The tint of the FD2 is okay-ish but far from decent imo.

From what I know, only Fireflies have the FA3 tint. Where do you plan to buy them from? Personally, I think DUV even on the BBL still appears kind of yellowish to me. You can see my test results in the Fireflies thread. I prefer DUV -0.02 to -0.06. Makes whites look whiter. Where did you get your SW40 from? Usually the SW40 is on the BBL unless you bought it from Clemence which is rosy but not as rosy as SW45K. I like the tint on the Clemence sw40 alot. Much more so than the SW45k. Btw, only the K versions are guaranteed rosy. With 4000K, I never think it looks magenta even if it is very rosy. With 4500k, it can get slightly magenta with very negative duv depending on how your eyes are adapted because 4500k contain more blue than 4000k.

What I think would be awesome is if you mix the SST-20 2700K with the SST-20 4000K. Should end up about 3500K but with decent rosy tint. Another possibility I was just dreaming about is mixing LH351D 2700K with LH351D 5700K 90CRI.

Maybe they’ll be willing so sell some emitters as addition to an order.

User Azhu sells 219B’s, so if I’d were to buy 291B from him, either SW35 or SW40 I will from him.

However switching from SST to 219B will means I’ll lose both output and range I’m afraid. And someone said to me SW40 will be violet under plain narrow TIR. I highly dislike the SW45K because it looks violet and grey to me.

The best led I saw up to date was a XML-2 5DA4 from Convoy under a pebbled TIR. It was noticeably less rosy than the HI 5D but still under the BBL. Very neutral, just perfect.

Mixing with rosy 3000K form Blue Swords group buy wil have a better effect on the tint.

The problem is I started liking 4000K again for daytime urban exploration when switching from daylight to 3500K or less is annoying.

Azhu’s Sw40 is not rosy. You can look at his first post in his GB thread for his duv measurements. Except for the sw45k, they are all on the bbl.

Does anyone know if the 5000k XPL HI version has always been available in the V3 bin? For some reason I remember it being V2 before..or maybe that was the 4000k which is currently V2.

Not sure but IOS has the XPL HI 5000K's (3C) in the V4 bin - I just ordered a few.

I bought a used one so I don’t know the bin. I think fireflies just got the V3 cause it was V2 when I checked a few months back and Neal also still has the V2..so maybe mine’s V2. The person who I bought it from said he purchased it on October 2019. This probably doesnt help but the brightness is exactly double of the 5000k EC01. Sustainable output also seems to be very similar. It’s not that important but it would be nice if I could find out somehow. Is there a difference in tint between the V2 and V3?

There shouldn't be, but there's variances. V2 and V3 are output ratings, not tint, so it's output lumens, disregarding the tint.
