Hi guys, new to the forum after trying to find a simple answer to my puzzle and just getting more and more confused.
I know some will think the answer is simple but I ask you to bear with me please and offer the simplest explanation with drawing if poss, so I cant fail. (I hope). I have used 12v supplies before to wire up3 and 5mm leds with resistors but these are completely different IIAC.
Thanks in advance for any and all replies.
I have the following that I could use (the drivers purchased after advice).
10 Bridgelux 3w cool white Leds Voltage - min 3.5 - max 4.5v Current - 750mA
6 Bridgelux 3w Royal Blue Leds Voltage - min 3.5 - max 4.5v Current - 750mA
4 Bridgelux 3w Deep Red Leds Voltage - 2.6-2.8V Current - 800mA
3 12v (constant v) 24w 2 amp dimmable psu eBayUK item No 390556572105
3 12-24v low voltage dimmers eBay UK item No 151055417940
Thought I might use these the old "add a resistor and go" way uh oh!
Following advice I purchased 2 of these drivers, 230vac to 8-48v 1000mAh
eBay UK item No 231012564360
I want to make two tank lights, one for frags with 6 white 4 blue and two red
and one for a Quarantine tank with 4 white 2 blue and 2 red.
I did want to make the reds and blues dimmable but the power supplies arrived and are apparently not dimmable so is there anything I can do to make them dimmable.
If any one can point me to my answer I will be extremely grateful.
