Hi there, welcome to BLF.
I’ve found that for underground photography I like a zoomie with as wide flood as possible. When looking for such zoomies it’s my experience that almost no one here at BLF really cares about flood width, it’s all about the fully focused end which has little interest to me.
Anyhow, my favorite zoomie for photography is a cheapo one but with replaced LED and driver. Actually, how I found BLF was through searching on modding lights because the cheapo zoomie has irritating mode change features, annoying blinky modes and a cold blue LED. If wideness of flood beam is of importance, and you can consider giving LED swap another try (and maybe driver swap too), then so far I haven’t found a zoomie that beats it. I mention it this thread: Zooming Model List (2018 Updated) Tell us about your newest zoomie! - #90 by Mike_C (post #90).
I also use a variety of fixed (non-zoom) floody lights depending on the photo. I have a thread where I post exploration photos every now and then: Exploration photos with my flashlights
The first seven are all taken with fixed lights with MT-G2 LEDs. The 8th and 9th photo (wagons/carts and tunnel) are taken with the cheapo zoomie I mention (with replaced LED and driver). I also built one of these zoomies with a MT-G2 for an exploration buddy, it’s a pretty decent light but requires 2 x 18350 cells. I’ll hold on building another until I can get a working boost circuit so I can use single 18650s in it: Mod: Zoomie with MT-G2
If wideness of flood is not so important, then the thread I linked to first could be a source of information for you. Plenty of decent zoomies in that list: Zooming Model List (2018 Updated) Tell us about your newest zoomie!
