I received my CL1H V3 R2 yesterday, and I tried putting the P60 sized reflector/LED pill assembly into my Ultrafire 502B this morning. What a big difference! It turned my marginally OK light into a pretty dang killer light. Is there a cheaper P60 host anywhere? I'm going to have to order more reflectors and pills. Sigh.
Oh, I forgot, I managed to navigate to separate reflectors and pills on the website and placing the items in my cart.
You can access the available pills from the "Products & Upgrades" section, but the way to access reflectors is through "Cree Drop-in Modules" and from there hit the "Reflectors" portion of the UPGRADES section. I hope this helps.
