You can take out the brown reflector before you dedome the led if you want, it is a little bit tricky but with some pliers its possible to remove intact and reassemble afterwards.
EDIT
Here is a picture from Tom E that helped me take it out safely.
Dealmetic have sold 10 of these lights since this review was published and now only have 4 left.
They do seem to re-stock fairly quickly though. I think they are going to need a lot more stock, quick!
Definitely a contender for this years BLOTY* award. (If there was such a thing)
Thank you for the review. Such good pictures that really show what is what here. TY :-)
For those feeling that advanced modding itch I'll post some results of other modding endeavors to undertake on this host for us addle minded light nuts over the holidays.
Let me try a handwaving answer; someone I hope can point to a source with a proper picture of the structure and light path that will be clearer.
All “white” LEDs use a blue-white emitter underneath a layer of phosphor that glows yellow-white.
The light path going through all that plus the lens is giving you an image of the original source.
If you were to look very closely at the emitter (don’t do this without a filter, it’s too bright) you’d see that variation due to the difference in thickness of the phosphor (and maybe of the dome as well) and the variation of brightness of the emitter underneath. If you look closely at the tightly zoomed image of the emitter it’s slightly brighter on the side where the wires connect, and slightly bluer.
If you look at the widest zoom you’re seeing almost none of the central, slightly bluer, direct light, and more of the edges that are lit mostly with the phosphor color.
You also get bands of bright/dark/bright along the edges of the circle, there’s a name for that effect that I’ve forgotten.
Checked my other zoomies and they all have varying amount of yellow band. With Zeusray this effect is more pronounced because it’s the brightest zoomy and thus contrast is more pronounced. Thanks for the answer.
