I've been looking for some high power IR LEDS and seen that some suppliers offer the same LED but with various number of "chips" in the LED. I'm confused what exactly "chips" mean. If you look under "Model Number" on this page you will see the different chip options:

It seems like in general the more chips you have the higher power, but there is a 1W single chip IR lED option as well as a 3W single IR LED option. I also don't know what would be the pro/cons of lighting with difference power LED's to get the same output. For example, if I need 6W of LED lighting I could use one 6W LED, six 1W LEDs, or three 3W LEDs. To make the best lighting choice for number of LEDs to get to my required output, guessing I should look at cost differences for using differnt chips, temp differences when running one chip at high current vs many at a lower current, and making sure that if one LED breaks the other will continue to work instead of them all going out. What other considerations should I have?
