Hi. Can anyone help me please.

The HQ1 lights keep going on and off every 15 to 20 minutes. The cooling fans in the lid are working OK. Could it be the thermal cut out? Would appreciate any advise as to what is wrong.

Your hunch may be right. The weather had been pretty hot these past week. There might be insufficient cooling for the MH thus setting off the safety cut-off device mounted on the reflector. JBJ recommends fan replacement every 12 months, it think.
