Re: FS: SST-50 / SST90 Deluxe Heatsink ***Ready to ship***
In regards to my question, Mac has mentioned a key point, "stock reflector", not sure if he has noticed the same results that I have. I've tried modified Carely reflectors & a KD MOP reflector (copy of FM's reflector). All of these reflectors are shorter than the stock Mag reflector. Although I have not actually tired FM's reflector I'm assuming it is the same as the KD is a copy of it. In a Mag D LED mod there is not an issue. In a Mag C mod because of the shorter length of the reflector & the Mag C head does not screw as far down as a Mag D they will not come into proper focus in a Mag C LED mod. The issue is not in relation to the Mag bezel screwing all the way down.
I have yet to find a metal reflector that is the same height or longer than the stock Mag reflector.
I encountered this issue long ago when using a Hotlips heatsink & a PMR reflector. Back then the hotlips heatsink & PMR (modified Carely reflector) was all that was readily available. The PMR is alot shorter than the Mag reflector. Then came along the O-sink, the DHS, & your (Britelumens) heatsink. The O-sink & the DHS are pretty much based off the Hotlips with pretty much the same dimensions. The pedastal height on these heatsinks is .116-.117" both C & D size. I have never used one of your heatsinks so I can't comment on them.
In a Mag D the back of the stock reflector (with the cam cut off) can bottom out on the heatsink with the head screwed all the way down. In a Mag C, the stock reflector (with cam cut off) can not bottom out on the heatsink cause the head does not screw down that far. With Luxeons, SSC P4s, & SSC P7s in a Mag C with stock reflector it will still come into correct focus. With any "shorter" aftermarket Mag reflector the optimal focul point for best throw) can not be reached in a Mag C using these heatsinks.
So to sum it up, what is the difference in height between your reflector compared to the stock Mag reflector? If shorter, it may not focus "correctly" when using the heatsinks I mentioned. Again I haven't used one of you Mag C heatsinks yet. How high is the pedastal on you Mag C heatsink?
Mac mentioned the SST-50 heatsink needs to be .2 taller than the P7 heatsink. I'm assuming he is refering to your (Britelumens) P7 heatsink? Of course the depth of the "face" at which the pedastal starts at makes a difference too. Here's a sneak peak of a SST-50 Mag that I'm almost done with pictured at best focus. I used a standard DHS heatsink & using the stock reflector I can achieve proper focus. No additional height added to the pedastal, emitter is sitting right on it. The pedastal height of the standard DHS & DHS P7 heatsink are roughly the same. If I had a reflector that was any shorter than the stock reflector in this one it may not focus correctly.
Hi darkzero,
Could you elaborate? May I know if you meant that the reflector does not sit low enough for the Mag ring to be fully screw in?
With regards,
Jo @ Britelumens
Joe they look nice. Have you actually mounted an SST Emitter and tried to focus them in a MagLite? I found the pedastal needed to be around .200 taller than the P7 heatsink to focus properly and looking at the pictures appears the pedestal is lower than the lip of the heatsink.
It appears by the pictures to me that this will not work. I have built a few of the SST-50 LED's in mag hosts and to properly focus the LED using the *stock* reflector the pedestal protrudes into the reflector around .200 of an inch. It barely looks like you have the height with your current design.
