Cree Xlamp Grow-Light Schematic Design (Wanted)

That should do.
I do hope the regulator's heatsink on the back of the star is a little joke.

It will require, at the least, a cpu heatsink with fan.
Here's a case where more is better.

Yer Weeze I ordered the wrong size ,I was going to just use the hd heatsink ONLY but thinking about it I might add another fan + Sink !

Should soon have some more pics


Nice One Weeze :thumbsup:

Wired My ledâ??s in series on The HD Sink Plugged it into My power sup nothing happened so resoldered all joints :jointsmile: still nothing ,Booooooo!!

Any clues am I missing something?

Unfortunately I do not have a multi meter at home

[Weezard]

Hmm, Let's think about this.

You have 4 leds in series.
2 red, 2 blue.
Your spec sheets say red Vf = 10.5V avg.
and blue Vf = 6.5V, avg.

So, 10.5 + 10.5 + 6.5 + 6.5 = 34V.
The total min. Vf is 32V.

So, if your supply is enabled, and you are providing at least the minimum required Forward voltage, betta call da doc, you've gone blind brah.:smokin:
(They warned us when we were teenagers, yah)

My advice, (in braille of course),
Buy a cheapo meter, horse!

Meter gonna let you "see"
what's up wit 'lectricity.

It's electric, it's expensive,
you should be more apprehensive.
What, you no kea win dis bet?
why you work wit' out a net?!:wtf:

Nice pictures.

Aloha,
Weeze

Mo'betta now and lookin' good.:thumbsup:
Did not realize all 4 were amber. D'oh!:i feel stupid:
Looks like you have it sorted well enough.
No worry, sometimes I can't even spell parallel.:jointsmile:

It's the nature of the meds.:stoned:
Glad your vision is 20:20 though.

â??It's the nature of the meds.â?� Very true my friend !

Added a blue 3w Star to the centre of My lamp looks great !
I have now switched off My 14000k 150w & 70w 3600k halides in My veg room and replace them with My new led light + 4 Blue gu10s they have been on for at least 24 hours now over my clones with no adverse effects at all in fact I would say the plants have perked up a little !

I have a Energy monitor and it shows that I am saving about 7p an hour ( was around 15p per hour now around 7p) so Im happy with that !

I am now making another light to hang over my mother plants with 2 amber 2 red and 6 blues






Peace :hippy:
