its been coming for some time now....but tyler has recently been increasing the Rate of Lighting Upgrades in the City.
Up Until Recently AE 115's an AE 113's were the Prime Replacement in Tyler.
On the Main Roads the 113/115's replaced larger,older cobraheads (EX.M400R2,OVM,125)
On Side Streets the 113/115's replaced Nema Heads
starting Early in 2009 GE M250R2's started appearing at a Rapid Rate.
on the Main Roads the M250R2's replaced older small and larger cobraheads (EX.M400R2,OVM,125,113,115)
on side streets the M250R2's Replaced Mainly Nema's and some small cobraheads.
below is a list of Fixtures,their location and wattage/lamp type.
Nema-175 Watt MV,100 HPS on very Few - Side Streets,Private Land Security Lighting
AE 113/115 175 Watt MV,100 Watt HPS - Side Streets
AE 113/115 200 Watt HPS,250 Watt HPS - Main Streets
GE M250R2 100 Watt HPS,200 Watt HPS,250 Watt HPS - Main/Side Streets
the lighting upgrades also include the Traffic Signals in the Area.
The Earliest Poles were Double Guy Wire Arms with Bottom Braced Upsweep Arms
Presumebly with Mercury Fixtures in the past,but with current Popular Replacement models at the current time.
The Second Oldest Poles are Truss Arm Types with Intergrated Fixture Mounts.
in the same spot are Galvanized Straight Mast Poles with Intergrated Fixture Mount with Long Tapered Elliptical/Upsweep Type Arms
Note: By Intergrate Fixture Mount i mean the Pole has a Spot,Or bolt holes Predrilled for the Arm to mount to.
Later Poles used Straight masts,(Galvanized Finnish) however the Arm the Fixture was mounted to was Clamp Mounted to the top of the Pole.
The newest Poles are still Straight masts,but rather than a Galvanize finnish the Poles are finnished in a Dark Brown Finnish with Clamp Mounted Fixture Arms.
including the fixtures on the Arms,Traffic Signals in Tyler generally now use FCO Fixtures for the newest Poles,having Cutoff and Semicutoff on older Poles.
Newest Signal's have GE M400R2 FCO's and Cooper OV25 FCO's
Slightly Older Poles use Cooper OVF's/OVY's.
the most Recent Upgrade is to the Lighting Setup on the Loop 323 (Loop Route Circling the City)
The New Setup is Very Clean Looking,(Pics as soon as possible)
The Poles are Galvanized Finnish with Short Truss arms...with GE M400R2 FCO Fixtures
the Poles are in Two Fixed Heights....it appears 30 Feet for the Taller Ones and 22 For the Shorter ones.
