Philips CDM-R111 vs Sylvania ESD111 3

Two 70w R111 metal halide lamps running side by side.
On the left is a Philips MASTERColour CDM-R111 and on the right is a Sylvania BriteSpot ESD111.

Both have 24 degree beam angles and both are 3000k colour temperature with the Philips having a CRI of 85 and the Sylvania boasting a CRI of 90 which is interesting as the Philips is a ceramic lamp and the Sylvania is a quartz lamp.
The Philips looks a lot warmer in the photo but that must have something to do with the reflectors as in real life the colour of the beams are only slightly different.

Both lamps have very good main beams and both have slight shadows or reflections from one of the lamp lead wires.
Overall I think the reflector of the Sylvania looks the best, it just had more sparkle to it which I would chose over the Philips if I was going to install some of these lamps.
The Sylvania has a noticeably cooler beam as it is a dichroic design. The pressed aluminium reflector of the Philips directs a lot more heat forwards.

Note the lamps are not perfectly aimed at the camera lens hence the uneven illuminated of the reflectors.
