I am comparing Interlectric lamps SS73 MAX 6500 120 watts to Genesis lamps F73-T12-HO-120 watts, I have Sun/Dash 232 GF beds. I have approximately 350 hours on these lamps. Initially at 50 hours the UV meter readings were 21.5 for the Interlectric lamp and 20.4 for the Genesis lamp. Now my readings are 14.1 for the Interlectric lamp which is 65%and 18.1 for the Genesis lamp which is 88%. I was under the impression that you should change your lamps when you expend 30% of lamp life. I I spoke to the Interelectric service dept. and was told to me there readings were fine and their lamps were rated for 1000 hours and should be changed at 750 hours. If I would follow their rule their lamps would expend over 50% usefullness. Costumers are asking already asking why is there a difference between the beds.
