Anyone else have outdoor beam shots of the Oslon Delta? Seen a couple here, but fewer than I’d like to really get an understanding of this light’s capabilities, especially in comparison to other similar sized throwers.
Possibly someone has a GTminiVN, u22vn, CATvn, or D1Svn with outdoor side-by-side beam comparisons vs the Oslon Delta?
I received my Delta today! Awesome awesome awesome! Haven’t taken it outdoors yet, but seeing the center hotspot on a white wall vs the old MH20GT is just... no words.
I do have one major gripe however, that I didn’t imagine would bother me prior to owning this light. The donut-like corona that surrounds the main hotspot is very unpleasant/distracting. Perhaps if the corona was an even flat layer, it wouldn’t be a problem. But because it’s super intense hotspot -> weak donut -> sharp outer edge of donut -> weak spill, the ring is a bit bothersome on a white wall. I know it won’t be visible outdoors past 50m or so, but it will probably get 50% or more of its use indoors unfortunately.
More than ever do I desire to have an oslon thrower with zero corona, merely hotspot to weak spill sounds heavenly! What type of reflector/setup is needed for such a thing?
Tomorrow I’ll plan to take it outdoors and have some real fun!
Even more intriguing is the beam pattern of triple/quad/xxxx osram white lights... If an ROT66vn can get past 250k+ lux (or anything under 50mm head) I think that form factor / beam will be my next purchase!
ROT66 with SST20 LEDs makes for a huge-broad hotspot with minimal spill and really no corona to speak of. ROT66 with The White Flats in it will probably make for a less huge, but still very large hotspot, with very little spill and also no corona. The larger optics in the D4S make for a smaller hotspot with large corona, I don't like it quite as much.
With reflectors, what you want to look for to have a light with minimal corona and large hotspot, is a reflector that's shallow and wide. The Catapult V6 with the XHP35 HI makes for very little corona and a filled hotspot. The Manker U23 with the Black Flat will probably do something similar. You get a third the output, but the same throw distance, smaller size, and better heatsinking.
