Philips Delta Lantern Installations

Philips' Delta was also sold as the Philips 2620, and is the successor to WRTL's 2600. In fact, they even shared the same bowl! These were available in SON, metal halide, or CFL. Unlike the 2600, a separate post-top spigot was not needed as the lantern its self was side-entry and post-top.

As spot-replacements for failed mercury lanterns, a plethora of SON lanterns have been fitted along Adams Street. The oddball in the mix is this Philips Delta. As far as I know it's the only one in this area, failing that, the City Centre as a whole.

This close-up reveals the similarities between the 2600 lantern and the Delta.
