What does forward and reverse voltage mean ?

Asked by: simon
The reverse voltage is the voltage drop across the diode if the voltage at the cathode is more positive than the voltage at the anode (if you connect + to the cathode). This is usually much higher than the forward voltage. As with forwarding voltage, a current will flow if the connected voltage exceeds this value.

what power supply would you recommend for 5 in parallel and/or series?

Asked by: Benn
The one in the link below would work fine when set to the correct voltage and amp's depending on how you connected the LED's up. http://www.maplin.co.uk/p/80w-switched-mode-dc-multi-voltage-slim-bench-power-supply-n27gg

Hello, what transformer would you need for 9 of these lights?

Asked by: Bubbsy
The LEDs use a voltage of 3.6v @ 100 ma, The power requirement would be determined by the way you wire up the LEDs 9 LEDs wired in series would require 3.6v @ 900 ma 9 LEDS wired in parallel would require 32.4v @ 100 ma Unfortunately we do not have a transformer with either of these exact outputs. This kind of enquiry falls into out project circuit design category and as much as we would love to be able to help here, as Technical Support Advisors we cannot offer design project advice or assistance. We are more than happy to locate products and support you with your purchases but we are not able to design entire circuits or projects for you. If you do have the design/circuit information detailing the value of the components needed we will be happy to locate these for you.
