this is what the Mega-Ray 100 watt wide says on the box . isn't 150 the ideal MW of UV to shoot for . My basking area is 14'' below , but My Rhino back is 2'' /- higher . I can lower it further if you guys think it should be .

'' MINIMUM distance setting of 12" will produce approximately 150-200 microwatts per square centimeter (uW/cm2) of UVB and 900-1200uW/cm2 of UVA.''

Thanks !
