Great work!!
I love my UF-1504. Got it from MTN as a DIY host and theirs is a generic unbranded version. Paired with a FET boost driver, XPL-HI V3 and IMR 26650 its all I need. It ewasily far out-throws the range of my own vision, which admittedly is very poor, even with my coke bottle glasses. For the price I paid, and its overall size I don’t think I can get more peak lux AND open flood when defocused. I want to try the UF-1508, but my understanding is that it doesn’t zoom far out at all, so its only good for one thing.
For the longest time I hated zoomy lights, but the 1504 changed all that. When it is de-focused it has a very wide flood beam… very versatile and useful.
Thanks, and thanks for posting about your 1504, nice photos!
I wonder if one was built like yours but with regular XPL (not HI) would it have more light/brightness in full flood mode, but still have some good throw?
I have an interest in zoomies as I use them for underground photography, and the wideness of the flood beam as one of my main interests. I’ve clicked on all zoomies in the OP and I think very few of them can match the wide flood of this one: https://www.fasttech.com/products/1601/10002775/1206500 (comes in a variety of different “brands”).
I have quite a selection of zoomies and so far this one is unrivaled in terms of wide flood, so obviously I think your list is incomplete without at least one that uses the same host.
Thanks for the list though, I’ve spotted one or two that might be able to compete with my favorite and will order. The Warsun looks particularly interesting because of it’s sliding distance. In a sliding zoomie the sliding distance is a tell tale sign of how much the beam width can be adjusted. After all the zoomies I’ve been through I know if a sliding zoomie has sliding distance of less than 1.5 cm I don’t have to bother with it.
Good question… I don’t know if I’ve ever turned one on in stock form before ripping out it’s internals. I have a few unmodified still intact waiting for drivers so I can check. It will be after the weekend though, because I’m hitting the road as soon as my coffee is finished.
Hard to say without actually building one and comparing. Lots of zoom-light comparisons on BLF, and afiak none of them really focus on the flood beam performance.
FWIW… I found this thread very interesting from Argo, direct comparing the 1504, Z1 and 158 using de-dome emitters.
