I have a Led Zep Moby Dick Tinity heatsink for sale. It is Natural HAIII Coated $85 Shipped (US)
Same Heatsink used in this light
I can Provide all reflectors for this for $50 addtional (3x XR17 3x Fraen Narrow Beam)
I can also supply the Fraen reflectors modified so that you can use SST-50 LED's instead of the Ostar's. I can also supply Q5 XR-E's and SST-50 mounted on stars for additional cost.
