These are definitely not Philips Iridium gen4s. The Philips Iridium gen4 has a much thicker body and is slightly less angular, plus the spigot mounting is completely different. I’m not sure what lanterns these are, but my closest match is the Candela Nova. The same lanterns can be found on Bethnal Green Road illuminating the pavements.

Just seen the Google Street View images of the Philips Iridium gen4s and I gotta say that they’re stunningly designed lanterns. Much better than their predecessor, the Iridium gen3. Just wish they were even more widespread in the UK instead of lanterns such as Urbis Axia 3s, then again they’re probably more expensive.
