SWL overheating

Hi Guys;

 

I have two electrical services on my property. The house is one and the outbuildings are the other.

 

A can control insteon stuff in the outbuildings from the house (which is great) but I noticed that the SWL was really hot after it was on for a while.

 

There are 3 big old clear bulbs that are on the SWL and I can't see the wattage of them as it's worn off. I assume they are 100 watts each. (has anyone ever heard of 150 W or 200W bulbs?)

Being that, the SWL is rated for 600W.

 

I haven't had time to troubleshoot by putting new bulbs in the sockets and seeing if that solves the issue. I'll try that tomorrow.

Has anyone ever had SWL heat up and if so, why?

Hi Drew,

 

SWLs get really hot if they are driving loads equal or higher than their supported wattage.

 

With kind regards,

Michel

I have 150;200 and a 300 watt Light bulb. Not that I have them in a circuit right now.

 

The heat is generated by the electronics in the SWL. If the dimming SWL there is a triac that regulates the level to the bulbs. It does generate heat.

If it is mounted in a plastic box and not a metal one it may even get warmer as I believe some of the heat spreads through the mounting ears to the box.
