Calculating the Power Loss, consumption and Lumes of an LED circuit
Hi Everyone,

This is my first post and I hope to work with you on this to gain a fuller understanding. I'm currently designing an LED circuit with 60 3 watt LEDs.

Input power is both 120VAC for North American and 230VAC for other countries. I know this is pretty basicbut what is the best way to calculate the real power being delivered to my LEDs factoring in power losses from the LED drivers? I then want to convert this to the actual irradiance for the given area. I would also like to factor in the LEDs efficiency as well.

Professional designers would use circuit simulation software to evaluate performance including power losses. There are numerous safety considerations in such a circuit. Can you help us understand your experience and objectives. Is this a DIY project, or are you designing something for commercial sale?
