PhlatLight new SST-90 LED

Candle Power Flashlight Forum

Help Support CPF:

How much would you charge for one of these that is set up to run the SST-90? I may be interested in buying one to try out and possibly buying more to put into some driving lights I am working on right now. BTW, is there anywhere to get an SST-90 right now?

That does appear to be a very elegant solution to avoid thermal runaway. I am tempted to copy your design. I'd have to figure out how to mount the thermistor differently, as I plan to use a Brightlumens heatsink and a bare SST emitter instead of the SSR star. Maybe some thermal epxoy to mount it below the post would provie a similar distance from the emitter and thermal contact? How robust is that thermistor, can it handle many thermal cycles and what max temperture? Thanks again.

I use very simple solution - voltage regulator with decreasing voltage with increasing temperature.

It contains one thermistor (1kohm) parallel with 510ohm resistor and serial with 100ohm trimmer for exact setup trim pin of LDO10C driver.

You can see values on this picture:

Reporting in,

Just received my Top Bin GN201 (The highest Bin), 57K SSR-90.
& finally finished my mod.
This is much brighter & much nicer tint than the sample SSR-90
I bought a while ago from CPFMP. It beat out my Mag 85::twothumbs

For more out door beam shots against Mag 85, here is the build thread:

I got a confirmation my SST-90-W65S-F11-GN102 (PHLATLIGHT WHITE LED, 1000 LUMENS, CCT 6500K, CRI 70) has shipped from Avnet.

I told you it wouldn't take 26 weeks!

Funny thing is, it's not listed on the site anymore. Anyone know where we can order the premier bins from now?
 
Being playing with a SST-90 amazing LED in my book

Until my PSU killed it 😡 found out PSU has no regulation of voltage under low load... darn thing dumped 14+ volts into it on a later test when I flicked the
PSU switch the cracking noise was not a nice sound to hear :sigh:

Still had it whacked up to 11 amps at one-point but heatsink started getting toasty well toasty in my book I'd say no more than 65Deg.

My testing was using this heatsink... http://www.enzotechnology.com/cnb_r1.htm

45mm diameter - does not come with a fan but you get the mount to add a 40mm Fan which I will.

So my project now on hold prob until next year but hopefully by then it will be easier to get them on an optimised binning.

As for the LED very impressed by its ability to handle low light running to extreme output running while maintaining the colour purity.

Would be nice if the could do a small dome version like the 5mm stars like the luxeon cause I now quite fancy a multi-unit 3 or more SST90s on 20mm-22mm optics in high power SPOT mode then some backing up Leds of less power or even SST90 on a mixed mode control to give a wider beam output.
 
I was wonder which one of the SST-90 LED's is the best for a 3D mag mod? Which one gives the best light? Is it even possible to use a 3D mag to drive a SST-90 at 9 amps? Do i need to use a driver or will it run on 3 1.2 volt D battery's? Or should i use a different host? Any help on building this flashlight would be helpful.

with only 3x1.2v D batteries and direct drived will be really really really hard get 9 amp

4x1.2 its better option maybe with some resistor or circuit for limit the current at 9 amp
 
I just received my SST-50 from Avnet:

SST-50-W57S-F21-GJ200
PHLATLIGHT WHITE LED, 500 LUMENS,CCT 5700K, CRI 70

Now I need to find time to make a host for it :devil:

Will,

I'm eager to get your impression of the tint of the 5700K Phatlights compared to the neutral tint (4A) MC-E. After you've had a chance to play, please let us know which is warmer and which is cooler. Thanks!

We just ordered and received in less that two weeks 51 of the SST-90-W65S-F11-GN102 LEDs from Avnet. 51 is where the price break was. They come in a package of 25 LEDs per blister pack, so one would assume that Avnet has 24 more in stock.

I like the glass dome as the gummy bear domes of the other LEDs are hard to keep clean during assembly and must be washed with isopropyl alcohol. We also had made a one inch diameter PCB with mounting holes in the star MCPCB pattern. Hope to start testing this setup for the SR2000 light in two weeks using an adjustable output 9 Amp drive circuit and a 2 inch reflector. We have a 38120 3.3 volt FePO4 Lithium-Ion battery as a power source. Overall length will be under 11 inches with a 2-1/2 inch diameter head and a 1-3/4 inch diameter battery compartment. Hope to have this done and ready by the end of November, (maybe).

Nice work Curt. I didn't know PEAK was working on such a project.

Darn you for reading my mind. I just ordered 4500 series sst-90 to start a build, but I was aiming for a 12 amp burst mode.


It's nice to see a builder using lifepo4 batteriers. I have been planning to use them exclusively in all my lights because of the high life cycle and light weight and environmental friendliness. What I really like about your design is the use of only one battery. That makes charging so much simpler even though it requires a well designed regulator that can handle high current. Another bonus is it will be much easier to change batteries after a long night of cooler raiding at the river.
 
LB:

The 38120 battery is not what you would refer to as light weight. At 11.67 oz or 331 grams it is however a powerhouse. Power density is 10 Amps and a discharge capacity of 100 Amps. You could weld with several of these. They are extremely well made and have a 6 mm tapped hole in each end. Cost is about $32.00 USD each. We are hoping to get close to about 2000 Lumens out of this light. Primary usage would be for Search and Rescue type operations. I have a 3 D cell flashlight that is 10 inches long with a 2-1/4 inch diameter head with a PR bulb. The SR2000 should produce a little bit more light.

Curt - I would be very interested to follow the development of your light. Please keep us updated.

Everything is designed around the optics and not the LED, and that is true with all new flashlights. When my samples arrive and I will then get a chance to evaluate them for the best results. Then I can finish the finial mechanical design, make prototypes and do the assembly for final testing before production parts are produced. Preliminary design drawings are on the RMSK web site.
