Are LED Lights Really That Good?

• Better efficacy

Better efficacy – – Less power needed to achieve HPS light levels Less power needed to achieve HPS light levels

• LED compensation

LED compensation – – When one LED burns out, remaining LED When one LED burns out, remaining LED’ ’s s compensate for loss compensate for loss
