Trial and error - moonlights

Hey guys we had a international drummer come out to S.A had the show in Durban last night we did the sound and another company did the lighting they have the new LED par can lighting wow they bright!!!! They have 72 red 72 blue and 72 green total wattage 28w made by HP. Just with the 72 blue light on and no reflector its bright.
and no heat. The guy was saying that with all 216 LED's on it the same as a 300w MH.
 
this is coming along good, a bit slow but good, i was a electrical technician as well as a mechatronic engineer for a year, so i did lots of circuits, it was a year or two back but i think i can remember what is the story Diodes aka the LED in this case. I may be wrong, i'm just seeing this going back and forth so hopefully i can help clear a few things up:)

As far as i remember, they need a 0.7V drop across the LED to function, thats how they still worked well at 1.5V, The resistor in the circuit does two jobs, its drops the required voltage over the LED to spec and it regulates current flow so the LED doesnt burn out. AS far as thalions idea goes of putting a few in a line across a 12V supply, is it possible, but you will still need that resistor to regulate current. So if we put say, 10 leds in a line, it would mean that out of the 12 volts they would use up 7, and the resistor would need to take up 5, so it is possible, it just requires a bit of tinkering.

Hopefully i remembered correct on this, feel free to ignore this if i'm wrong:)

You can even run 3v 5mm LED's off 220v AC, buy using a resistor and cap.

guys only had time last night to sort some of the wiring for the leds, i managed to get
2x computer sound card cables i had left around and made use of the both end block
connectors mainly as the led pins sit neatly and comfortably in it and the block connectors fit exactly inside the down lighting slot for the bulb...

im basically going to try out 4 led at once in the downlighting frame
and should the need be then i would increase it;)

hi scubaninja

yes im progressing but slow:( i guess time isnt on my side, but im getting there, i dont like to rush either as i can miss out on some good ideas....;)

so tell me as you are more experienced in electrical due to your capacity before
would this diagram be correct in its creation


 
OCELLARIS I have ordered one of these boys below, any comments ?

so warr is this the colour you getting?
 
Hi Warr how much is cheap? If only it was a mix of blue and white these could have been very useful!
