I bought a Heath Zenith floodlight that runs on 2 PAR38 bulbs that equal 200 watts,but intstead I ran the fixture on 2 A19 bulbs that equal 135 watts.

Are you using 67 watt miser lamps?

No,actually I used one GE 60 watt bug lite and a GE Xtra Life 75w bulb.I will upload a picture of the fixture  soon.

I have the same light. the hoods somewhat protect the A 19 bulbs from the weather. I used 100 GE soft whites.

Good to know.Which company made your fixture?

Hope there are no plastic parts inside. The PAR lamp reflects the IR out as well so it heats the fixture less than A lamp even one of way lower power

@ lightguy it is a utilitech from Lowes, the fixture is all metal and the socket is porcelain it seems well made but time will tell.

There may be even important, how heat resistant are the wires connecting the sockets. The socket may well be PK, but if the wire insulation would melt from the high temperature present there, the whole thing would fail...

 most wire is rated at 90 C rating some can use 105 C but not very oftem
 the older stuff you have to watch out 60 c rating that can be a problem

 even though we use 90 C wire in houses but the code derate it to 60 C for resdential installment
 in most case.

IR hitting the plastic can heat it instantly to way more than 150C

even though we use 90 C wire in houses but the code derate it to 60 C for resdential installment
 in most case.

It is derated (to 60degC for a case), because the installation need a margin for selfheating by maximum current load plus the surge from the eventual short circuit condition (from the time the short circuit occur till it get's really interrupted by the fusing, the short circuit circuit current of multiple kA heat the wire up further) and after all of that the internal temperature should not exceed the real material rating (so the 90degC for that case). So in this view the 30degC is not as much...

I have used the light for 2 days in a row using the  bulb,and the light has not failed.Heres the picture of my light running.

The insulation plastic degradation is not a matter of days, but rather a year or so...
