Anyone understand what "4 chips" means? :?: Also, what does the 10000-18000mcd part mean, and why is that so much lower than the final total power output figure? :?: Iv: 10000-18000mcd @ 80mA, Total power 825,000mcd* Anyway, if we are actually talking 825,000mcd from one 55 degree 10mm...

Thanks dupaboy1992, that’s been great advice. :D I going to see what power adaptor best suits, and then wire it all up…( :!: ) It’s never going to be the brightest or cheapest way to light my tank, but when better LEDs come out I can have another go, and I just like the idea of trying...

Hi thanks again, this is a real help… :D …I think I understand, :? but predictably that leads me to more questions… 8O :?: Is the 132mW a set factor directly/proportionally related to the 330 ohm properties of the resistor? :?: As such, does the 68mW and 132mW remain constant...

Hi, many thanks for that. I didn’t think I would get a response that quick! :D Really good news about the 5A question, I will give it a go this week once I have the right power adaptor… So, to be absolutely sure I have got this right… :? … contrary to the manufacturer’s recommendations...

Hi, I read with interest the post about the potential for using LEDs for lighting up a tank with minimal heat. Part 1… My big problem now is how to wire up an array. :? I have purchased: 100 White 130,000mcd 10mm (Forward voltage 3v Min /3.8 Max /3.4v Typ. 20mA) 12 degree angle 100...
