SST 90 Dive light 3rd production

[H20doctor]

(disclaimer ): If you have Negative comments Or nothing Positive to say, do not post in my build thread .... Thank you.

So i have built 4 SST90 dive lights for people and id thought I would share some Basics on how I am putting these things together.. the hardest part is to get a decent Bin from Avnet, and the other is having them in stock ... I am useing alum 1 inch Rod from a local internet company that is a Dollar and inch.. I ordered a P7 reflector from Deal and slapped it in the Mag Host after having to grind it down , both on the reflector and the Mag cause it wont fit unless you do ... The driver is from George at taskled the HipCC 6 amp monster ... the battery pack is 12 volts sub C's from Allbattery...
as far as the beam goes , its pretty floody, and im not to crazy about it , So i am working on a better relector , and also possibly going to use a defocused Aspheric setup in the future... Total cost to build is about 125.00 US ...

show more of the cannister and are you using a toggle switch?

 

[H20doctor]

I have not put a Paint job on this Light due to the fact that I just built it yesterday .... I did use a toggle on this one, But now I only use reed switches on my new lights .. I feel a toggle switch is a fail point as boots get worn out and eventually tear , or get pin holes..etc..etc..

 

[jspeybro]

thanks for the pics.
I'm making plans to do something similar.
Which bin of the SST-90 do you recommend for a dive light?

[2stardiver]

so driver and batteries are in same space?
how much driver does get heat ?

 

[DaYerk]

Real nice one. I only would recommend thicker wires.

How is the front lens sealed?

 

[baywatch106]

why the segmented looking cannister? Any pics or info on how you do the reed switch, where you place it etc..

The bin is W65S-f11-DG-GN100

(why the segmented looking cannister?)
So i can attach stainless clamp to the canister , and then attach it to my Back plate and wing ..

so driver and batteries are in same space?
how much driver does get heat ?
Yes there in the battery canister ... The driver does get warm But its cooled off by the Water here in Puget sound 52 Degrees, Run time is 2 Hours

How is the front lens sealed?

I used 14 Guage wires for the Battery... the Led and the driver Has 24 Guage, you cant use thicker wire on george's driver .. the holes arnt big enough

the front lens is sealed by an Over sized Oring , and the same on the Light head... then screwd shut ...

I am going to start a New thread on Reed switches , with the next Build .. :)

When did you get a plate and wing? :poke:

looks like a great light man! Run time of 2 hrs should be sufficient for a night dive, does it take a long time to recharge?

(pardon me if the question is a noob one, am asking on behalf of my brother who is into diving and really likes your light)

Depends on the battery pack size and the charger output. With the right harger, you can recharge in a few hours.

It takes a couple of Hours to recharge ..I have 2 Battery packs just in case I do 3 or 4 dives in a day , or go on a trip for the weekend

Thanx for the pics!

Question - looks like you're using a solid alum. rod for the heat-sink, and running the emitter leads down the side: what is thermal path from big heatsink to m@g body tube? Great path from m@g body to surrounding water, but with the two wires insulating heatsink from contact with tube where's the heat go?

Best,
L

My question, as well.

Congratulations, though... You finally seem to understand the necessity of thermal mass. Thermal pathways, however, still seem like they need a bit of an improvement.

May I ask where you purchased your reflectors?

Reflector looks like Dealextreme.com P7 reflectors. About $5.

all the heat goes into the sink.. the alumin head when diving here in seattle Wa, is cooled off by our 52 Deg water.. The Heat is Liquid cooled by the water i dive in , I would never run this dive light out of the water ..

im using these 2 reflectors on my SST lights
http://www.dealextreme.com/details.dx/sku.12229
http://www.dealextreme.com/details.dx/sku.18841

I like the 2nd one better 18841 its got a nice tight spot, But you have to Bore the center out a bit to fit the diam, of the SST lens

Is that the better reflector you were working on (you mentionned it in the first post)?
