There are some heads that we use that are extended coverage, but only listed for light hazard. They have smaller k factors (5.6 and 8) than the EC heads that are listed for OH (11.2 and 14), plus they are about 30-50% less per head.

If anyone's familiar with this particular version of it I have a quick question: Ordinary Hazard group-1 is the minimum design allowed but they do give a couple exceptions. One is that QR & QREC heads listed for light hazard are permitted as long as OH-1 density is still achieved. What would be the benefits of applying this exception? Thanks!
