I have been looking into reflectors lately as I am searching for a good spot reflector for the Luminus CSM-360 led. The reflector in the Elektro Lumens light looks to be the 5* reflector from Illumination Machines, which I have posted about
HERE. The minimum order qty is 10, which I purchased, so I have some to spare if you want one. Overseas shipping is cost prohibitive but if you are in the USA or Canada we can swing it.
Lighting Science Group makes some reflectors that, while not designed specifically for the SST-90, could probably work. I have ordered one of their massive 151mm
Titan 10* viewing angle reflector from digi-key but it will probably be a couple months lead time, if they can get the thing to me. Supposedly they will have some in about 45 days. They have another
10* viewing angle reflector in stock but it doesn't seem durable due to it's design. (would be difficult to house it)
Beyond those reflectors, I purchased a 16* viewing angle
Ledil Barbara_S but it looks unimpressive, though I haven't tested it yet, and I also have one of those sst-90 reflectors from DX coming. My next venture is to get a reflector from phoenix electroforms made such that the opening is the focal point. Hopefully they can do that to one of their ready-made designs because I am not going to have a custom mandrel made etc. I will have to give them a call.
