Power draw for flexible RGB

The product data says that the forward current is 20 mA. Is that per 10cm/9 LED strip, or per LED?

Thanks! Also, do different colored LEDs use different amounts of power? Would the 20mA be valid for all in the strip?

different colours have different forward current i believe but to make sure i would wait till the boss gets back on that one
tis Better to have tried and failed than never to have tried at all

I blame spelling errors and my writing skills or lack of...... On fred!!!!!! My blood clot (yes I really did name it lol)

Just had the PSU out and it seems these are fairly conservative at exactly 12V, each channel (red, green and blue) drawing 15mA for the 3 LEDs. Meaning all 3 channels will run on 45mA at 12V for the nine LEDs. You have to push upto nearly 15V to get a 30mA current through the LEDs.
Also the connectors are called JSTs Japan Solderless Terminals, the ones on these strips seem to have the pins quite close together though so might be a different type.

Thank you again for the information. 45mA is nothing for the setup I'm going with, though we'll see how 70cm of the stuff works with my LED controller. :D

I'm having some difficulty finding the connectors on JST's site. Worst case, I'll splice in longer wire and use plenty of electrical tape. Ugly but functional!

Bit of a way down the line from this post but we have connectors for those finding it difficult to solder to the tape http://www.phenoptix.com/index.php/led-tape/connectors.html
