Beam angle for R lamps?

[JChenault]

I feel stupid having to ask this - but can someone give me a pointer to photemetrics for R lamps? Specifically the beam and field angles for the various sizes.

I looked on the GE and Phillips site but could not find the beam / field angles. Did a search through the archives here but did not see anything.
Thanks

Hate to promote software, but GE's lightbeam software may have what you're looking for. I know it has the PAR angles, it should have the R angles also.
Edit: Checked my computer and sure enough lightbeam has what you need. 67* for 300W R40, 54* for 120W R40, 62* for 65W BR30, to name a few. These are "nominal beam angles" according to GE.

Thanks. I downloaded the software and it is just what I needed.
