I vote Weez opens shop and let us bring the business to you.

I'll make way with a couple 55w arrays.

begood Weez.

be

Used this to Calculat Resistor

MetkuMods - Because you love your hardware!

came up with this

Are you planning to use this as a voltage regulator?

Nevah gonna happen, B.
I is re-tired.:rasta:
Was tired yesterday, will prolly be tired tomorrow.
Got friends beggin' me to build lights for 'em.

But, I'm a short-timer and will not go back into harness while the sky is blue and the ocean, warm.:jointsmile:


My life is so excellent now that nobody can afford to buy any of it.

'course everyone has a price.
Mine just topped $400 per hour. :D

Mahalo for the compliment, brah.

Well the plans coming together (A Team pun) I have found HDD cooler on flee bay that should do as my heatsink fans included only 3 Quid ...On the way ;)

Hopefully photos attached:stoned:


In theory My future plan is to try & make led supplementary light that would work of a HID hood say 250w via solar panel ( obviously trying to run before i can walk ) .. Imagine the potential !

Whats ya thoughts Weeze ?:thumbsup:

I'll spare you my "thoughts"
That could take years.:D

I do like that HD cooler.
I once glued six 5 W. leds to an aluminum LaCie hard drive case and stuffed it with CC drivers.

Still have the pup in case I need a spare clone light.

Cheers for the help Weeze :D

Yer was thinking of it got Schematic Design from the site but was way over my head :wtf:

'Prob another daft one' but could i use this to run the lot as a quick fix ?

AC-DC 12V, 2A Switching Power Adapter (110/220V)
- Power adapter for all Micro Power Supplies
- AC INPUT:100~240V
- DC OUTPUT:12V 2A 24W Max.
- Power Cord included
- 5mm/2.5mm barrel power jack


Nice one Weeze!! :D

Not safely. :(

Bad idea to use a 2A supply to supply 2A. continuously.
It will run hot, and fail early.

There's an adjustable 12V. 20 A. supply on ebay for $20 USD.
I had to slap a fan on it to keep it out of thermal shutdown for a constant 12 A. draw, but it is rock-steady with the fan.

Switching supplies are relatively cheap so best to go overboard on the powersupply for safety and future expansion of your array.

If you have the budget for it, (About $140 USD.),
I recommend getting a large constant voltage/constant current, digital readout, variable supply for building and bench-testing your lights.
If you only build the one light, you can use the bench supply to feed it, and you are done.
If you build more and better lights in the future you will know exactly what you need in a permanent supply by the readout on the bench supply.

You can find the bench supply by reading through
"Calling out to Weezard for led advice" by Crunchypants, (Dreaded Hermie).

Aloha,

GREAT MINDS HEY :thumbsup:

I found this for 15 squids :D

Hello Again ,. Got all the stuff I need now ( except red blue cree ) ,the power supply look like a quality bit of equipment (UK MADE:) and I think Im going to get a few more @ that price :)
Check out the attached 20w Amber in action ,didnâ??t leave it on long as no heatsink etc .

Do You think I am ok with the 8A supply Weeze ?

Cant wait to get building :thumbsup:


Cheers for all the help Weeze :D
