    PAR bulbs and Lumens question...

    Hi, I have been looking at some lights and am getting confused... Is a PAR38 light (90W) with 1200 lumens better than a regular 100W 1600 lumens bulb? I understand that the PAR light can be more concentrated and directed but which one is actually better to use? Thanks.
