Hi everyone i could really do with some help wiring up my aquarium light. Building a small led panel for my fluval edge nano reef aquarium and still really new when it comes to leds and wiring so if someone could help assist me with this it would be appreciated.
I picked up 5 10w RGB leds unfortunately in the wrong colour spectrum so im waiting on some more to be delivered. Why im waiting on that im going to try and make a panel up from these 5 10w red RGB leds.
Want to power the 5 10w leds using a 19v laptop power supply and wire them in series.
So my main question is do i need a resistor? im guessing the answer to this would be yes so what resistor would i need? and could i use one large resistor on the positive wire before it goes to the leds instead of wiring a resistor after each led chip?
Heres the specs from the led vendors page on ebay
Forward Voltage (VF): DC 10-12V
Forward current (IF): 1050MA
Out put Lumens: 800-900LM
Beam Angel: 140 degrees
Link to the led chips im using http://www.ebay.com/itm/5-10-pcs-10...essories&var=630103354735&hash=item53f70fbd1e
Quick overview
5 10w RGB leds
Wired in series
Run off a 19v power supply
Also i dont currently have star heatsinks for the leds ? anyone know if this could be a problem? i was thinking of possibly using thermal adhesive to stick a piece of thermal pad to the heatsinks im using then use a small amount of thermal glue to attach the led chip to the thermal pad? so the led sits between the thermal pad and the main heatsink.
Thanks for any help in advance and apologies if some of these questions are ridiculous lol.
