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.

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.
