We purchased these for a 10 m chamber. They are floods, not spots, but I
thought it worthwhile to forward.
They have an option for suspended mount, but we chose to mount them flush
to the ceiling. The emissions are so low that we can not detect any change
to the ambient (commercial freq range,

78 series regulators (except 78Sx which are switchers) do produce a little
noise but I expect you have them well shielded. There are, of course, 'quieter'
regulators.

Hi all.
Has anyone had experience with using LED Spot lamps in EMC Chambers?
What types/manufacturers would be recommended?

It's hardly surprising, is it? These lamps are not designed for the very
special EMC environment of test chambers. Lamps using a DC supply are
indicated

installed outside the chamber.

Hi all.

Would appreciate help in trying to solve someone's problems with noise during
radiated emissions.
Test Facility has just had all their chambers converted to LED Spots and
