Can I ask for clarification please.

I want to drive approx 30 LED's, each LED needs to be controlled individually so was thinking to hook up via 4 x ULN2803a, then each pin to a 40X2, this would be controlled via a 2.4Ghz R/C transmitter. Not worried about coding at the moment but should be a simple job to do.
Anywho, the question before I start making it, the 40X2 can give 90ma I understand, my calculations are to drive all the ULN2803a's should be 35ma. Is this correct.
Thanks in advance guys.
