DEFT+CST 90 but how?

[saabluster]

Well I wanted to get some feedback on what to do with a couple Phlatlight CST 90 LEDs I got a hold of. These are the top bin(1000-1200lm at 3.2A). The CST is really what people should be excited about not the SST. The CST has the die mounted directly to a large piece of copper. If I go balls to the wall it will not be something that can go into existing lights for various reasons. I will have to make a light specifically for this LED and the price will be high as it will need a special driver solution as well as work on the battery and heatsinking fronts. I could also sell it as a drop-in for existing lights with a driver to bump the output to around 3A. This may be usable as a tool and not just a toy so it has more usefulness but isn't as fun. What do you guys think? Toy or tool?

My instinct is to go right for the big guns. Though a practical app would also be interesting. The people demand photos!

What do you want to see? I already posted pics of the SST 90 in the DEFT a month or two ago.

Toy!

Make a pill and driver for my DEFT :poke::poke::poke::poke::D:D:D:D

By toy I mean something not practical for normal usage and would be a just a showoff light. . If I go wild I have to do some major surgery to a DEFT so it is not something I could make work with your light unless it was shipped back.

heat is a problem with the SST-90's you need a lot of mass to heatsink - the one I had you could weld with it @ about 4amps DD off 3 x 5000mah C NiMH cells with a 3' reflector :eek:

" 9A or greater"

How big of a heatsink are you planning? a few manufacturers are having trouble running those LEDs that high in portable flashlights. Solder melt yet? ;)

The heatsink depends on the degree of usability I try to design it for and what the final price would be. I could spend more time, effort, and materials to increase the allowable "on" time but would people pay for that? It is obviously much easier to just slap it in an existing light, keep the power down and call it a day.

I say go all out, and then sell it to me :twothumbs

Accidentally melting down some unused silver wear from around the house (that the boss wont see :D) would make a good heat sink for that baby :naughty: but only do it if your couch is comfy for when you get banished there.

Well it seems the push is for it to be on the wild side. Time to get cookin'.

Yeah, go for the all out crazy light. Active cooling anyone? haha

but I would vote drop in - way more versatile and would be IMO easier/quicker/cheaper to sell to the masse$ - but thats just me - the DEFT I found too annoying for my keyring :D

I think I will do one of both. Hows that sound?

 

[Glenn7]

I just noticed everybody is voting for it in the DEFT - you will need a big heat sink in there wont you? as the body is thin - and thats where the heat first escapes to before it gets to the big head/sink - just a thought :shrug: - or make a Alu fin coupling for the outside.

aaaarh! yes good solution :welcome: :kiss::naughty:

Are you still planning on a dedicated light for your other LED?

I still want to but since time and money are very tight right now I decided to make them pills for existing owners. jsholli and racerX have laid claim to them. I may revisit it at another time.

I smell a Maxabeam challenger..

Part of what makes the DEFT so entertaining is how unreasonable it is, so possibly having a giant lump around the emitter with huge fins all over the place would just be more of a good thing..

What? I missed this one. :mecry: I thought they were going to be new lights... :( It also excaped my attention that there were only 2.

Well guess I can dedicate that money to getting a custom SST50 mod done. I'd think an overdriven SST50 would throw better than an under-driven SST90. Higher surface brightness I'd think; what are your thoughts on that Saabluster?
