Re: XD-4 for sale
I take it that you must have the spec sheet for that tube, as that is is a very nice lp/mm figure (almost that of an XR5) which of course affects the figure of merit, which is also high.
Thanks.

Re: XD-4 for sale
Ah, yes forgot to mention that. I've got the Photonis datasheet with matching serialnumber.
Edit: I think it compares to 1400 uA/lm@2856K, say Omni IV.
