any mogul base bulb of matching wattage to the ballast.

[J Crew]

is a radium mogul base?

[power boat jim]

yes, radium bulbs do come in mogul (screw in) base form.

so this hamilton pendant is hqi then? i was under the impression that you must the the radium on a hqi ballast.

[power boat jim]

I have run all the type bulbs you mentioned (except for a radium) on my hamilton. the hamilton ballast should fire a radium also. HQI denotes a certain type of ballast ( I think) Hamilton uses a magnetic type ballast that will fire any mogul base bulb of matching wattage, as will an electronic ballast.

To help clear thigs up HQI ballasts are used to fire double ended HQI bulbs.Radium makes both type bulbs as far as I know, so the hamilton pendant is not HQI. If I am mistaken someone will correct me,probably pretty quickly.
