any multi SST90 lights yet?

[Bushman5]

how long until we see some multi sst90 led lights hit the market? MCE's are getting outdated, lets see something NEW! :sigh: i dont want to have to go the HID route...i like LEDS....

 

[csshih]

.. you know you're a flashaholic....

:crackup:

man, for multi-sst flashlights, we would need either giant battery packs, or a dramatic sudden improvement in current cylindrical li-ion technology.

 

[Bushman5]

I guess i'm just tired of millions of the same old lights with the same old output. Even my Jetbeam M1X is growing old to me.....(partly because i was expecting 700 lumens, and not a lousy 450 ) i want to see some real light when i walk down the street at night with my light. I want to turn 4 city blocks into blinding daylight and have sheeple cowering in fear as the broad swath of pure white lights floods over them.

I own a couple of Wayne's lights. This one is kinda obscene...

You're better off with an HID. To run a triple SST90 light, for example, you'd need at least 6 18650s to get any sort of efficiency and runtime. Plus you'd need a huge amount of heatsink and surface area to keep the LEDs cool. In this case HIDs are just plain superior as they don't require such drastic heatsinking. It'll be this way until we get much more efficiency from LEDs and less wasted heat.

I think that even with a single sst90 we are having more lumens than our eyes need... it is better to adapt your eyes to the darkness than using brighter light sources to compensate a poor night vision :D

You need to look into the CSM-360. :grin2: http://www.luminus.com/content1520 That's going to be a PITA to focus... but at least you can use a 4s pack of IMR cells.

The link does not work.
Maybe it is better to follow the main thread:

That light is NOT using the SST-90. Well not yet anyways.

Elektrolumens work with the SST-90 is in this thread. Note the 2 INCH LONG heatsink which does NOT fit into existing lights.

The appearance of a new LED do not automatically mean a new light as the optics optimized for the LED are usually not available immediately.

lol....it seems funny to speculate about multi-SST90 lights when the single hasn't been perfected in flashlight use yet. They simply produce to much heat without some form of active cooling. As illustrated by Wayne's 2" copper heat sink, when one of these is run at its full potention it's going to require the full space of a custom light larger than a mag. It's also likely that any such creation is going to be pushing the price extremes in LED lights just as the Kong-12 is now. I guess I'm trying to understand what aversion you might have to HID, especially when talking about the high end. A 40W Polarion X1 for example would be more efficient, throws much farther, and would be more compact, than any SST90 custom. It's also very close in price to the most powerful custom LED creations amd Polarion produces full output within 3 seconds of switching on.

Better link...

LOL... 12 x P7 and 12 x 18650... holy s you got to be f-ing s-ing me!!!!

That's the most crazy LED flashlight I've ever seen in my life!!!

I almost bought Wayne's 4 x P7 mag lite awhile back, but this thing is off the charts!!!

 

[neoseikan]

only one reason i will use multi sst ~to produce a projecter. but i think they dont have a good RI

 

[lumen_eater]

Note the 2 INCH LONG heatsink

i dont get this trend to larger heatsinks anyway. its not the mass or volume that matters ( at least not in terms of thermal equilibrium) but the surface area. so why are there no lights with ultra fine cooling fins ? I think with a light that has a proper design (from a thermalmanagment point of view) there is no reason why multi sst-90 should be impossible.
And the whole battery argument falls apart when you look at hid lights . They use even more power then multi sst-90 lights would and the batteries aren't the problem.

 

[tab665]

why not make a searchlight with the sst-90's. have a nice big rechargable battery body like some of the HID's do. if a 35watt HID searchlight can put out 3500 lumens, i think 3 sst90's could do it in a similar set up with just having to be driven to put out about 1200 lumens each, and it should run pretty good with the bigger battery. EDIT: i think the problem is a lot of people (not all) have the notion that if its an LED, then it has to be a flashlight. not a big bulky serchlight.

I don't see why people are excited about the SST90. It's a big LED, requires a lot of power, and a lot of heat sinking. At that point why not go HID, incan, etc? The surface area of the SST90 is so large you'd need a huge reflector to get decent throw. I like seeing advancements with the 1x1mm sized LED dies. I guess it just seems like a step in the wrong direction, at least for portable LED flashlights, unless you put it in a large spot light type deal. Why not make a 1x1 foot LED and we could walk around with a 30,000 lumen panel of light that just flood everywhere, running off 20x18650's or something? :P

I want to turn 4 city blocks into blinding daylight and have sheeple cowering in fear as the broad swath of pure white lights floods over them.

I'm sure that would go over well in a city. :P Probably wouldn't be long before the police stopped you and asked you to stop blinding people, cars, etc. :P

How about a multi MC-E light? :)

Fins don't work well if there's very little airflow. Even convection won't help that much, and adding a fan would destroy efficiency.

The battery argument doesn't really fall apart when you look at HID lights. HID lights are actually more efficient than LEDs. HIDs can achieve over 100 lm/W but SST-90s are maybe 60 lm/W at 9A. This will change with the Cree XP-G, but that will be one very, very expensive array of LEDs.

i dont think so. ther are no hid lights that i know of that have 100 lm/w or more

 

[csshih]

there isn't a point at all for multi SSTs.. at their full capability @ 9A each.. lets say, you need 3.. 27A @ 3.7V

if Liion cells can be driven @ 2C, then you can have roughly 25 minutes runtime with 5 (!!!) AW 2600s...... :sick2:

100AMPS!!!! , and this is with 100% efficiency/.....

that may be true but from an engineering standpoint there is no reason why it wouldnt be possible( also more like 20C but wahts the point in 3 minuts runtime ? :eek: )

MCE's are getting outdated,

really? whatever gave you that idea? :thinking:

Personally I think the MCE/P7 is the best we can have in terms of LEDs in flashlights...at the rate of battery capacity we have [batteries that constitutes as portable] using bigger LEDs would be analogous to putting a porche motor with a go-pad fuel injector and expecting it be to efficient while severely underdriving it.

Personally, a decent balance between battery life and performance [not considering rechargeable compatibilities] lies somewhere around the Q4 region of XREs...but that's just me.

LEDs of lesser degrees aren't as impressive in output and LEDs of greater degrees have more thermal instability issues than the benefits they yield to illumination. :whistle:

All third party and private modding aside, I once thought putting the MCE in flashlights are illogical and yes I admit I was wrong after the debute of the TK40...but I will take the same stance again for these SSTs if their ideal application is to be seen as flashlight LEDs:nana:

Instead of chasing after the lastest LEDs all day every day, can we go back to innovating applications for existing ideas like how CPF was back in the olden days? :shrug:

You're mistaken on this point. Some HID are over 100 lpw efficient. The higher the wattage the higher the efficiency when all other factors are equal. The Polarion PH50 is around 102 lumens per watt for example. Other HID's achieve even better efficiency that is about double that of the SST-90. For 2-3 SST-90s to produce 3500 lumens, you'll need about 40% more battery capacity for the same runtime as HID.

Regarding the heat sinking, it's not just volume of solid mass of the heat sink alone, but its size is also determined by surface area contact needed in order to transfer the heat to the body of the light. In other words, the heat sink is large because if it were the size of a quarter it would overhead before the transfer of the heat to the finned body could even take place. The thermal bottleneck, so to speak, happens at the junction between the sink and the body. The only way around this is the use a sink appriopriate to the heat generation of the LED, which in the SST-90s case, is a lot.
