[RFI] Metal Halide Bulbs?

[kd4e]

Two questions about Metal Halide lights:

There are commercial-grade fixtures above each of the
two doors that use the Philips M-90 bulb and also have
light-sensors mounted on top.

On Topic

1.  Are they a known source of RFI?

Off Topic

2.  Do the bulbs come in yellow?  (I haven't found any
	and may have to replace the fixtures or convert
	the fixtures, so I may use a yellow bulb as the
	bugs are attacking the house in the thousands at
	night making use of the doors an adventure -- plus
	they are finding their way in around the window A/C!

	OR is there a yellow film or spray I could apply
	to the lens?
