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.
Let me know how you enjoyed this little insight to whats going on in tyler. :)

Is the conversion mostly to HPS? Or it is to MH or anything else?

All New Roadway Lighting Fixtures in Tyler are High Pressure Sodium,at this Rate these Upgrades will more than likely eliminate Most MV in the City. :(

I hope those brown poles lasts long, because there was rows of brown painted steel poles in route 29 near me installed in 1990 but recently got replaced with galvanized steel poles because the paint was peeling off and the metal already had rusted!
Same goes for some lighting in Howard County...the 2nd generation poles (mid 90s) were painted brown (actually they call it bronze) but some got replaced with fiberglass bronzed colored poles but kept all of the first generation (80's to very early 90s) ones which were aluminum painted bronze

well the brown poles are catching on,the Newest ones are Shiny,some that are only a few years old are starting to Fade and dull abit.
i guess the pole color depends on the Municipality,in Texas State Owned Signals are either Temporary (or more or less semi-Permenant) Wood Pole Span Wire setups.
most newer ones are Straight masts,Clamp Mounted Arm,and Galvanized Finnish.
in cities Brown Poles are the Most Frequent Upgrade.

Here we just have plain aluminium poles. BUT in a small part of the city, poles covered of small green stones are installed. Also, some major roadworks are taking place and some nice red decorative streetlights have been recently installed. I should get a pic soon ;)
-
Here in where I live (Toronto area) we use a lots of different poles and arms but the most common is a plain concrete pole with an 8 foot aluminum tapered e arm on city streets.
On provincial freeways (400 series Highways) the most common(non highmast) pole is a plain galvanized steel pole with an 8 foot aluminum tapered e arm on top of a breakaway pole base. Before 6 foot galvanized steel truss arms used to be used.
Most streetlights in intersections are on galvanized steel poles like on the freeways. In the past couple of years decorative streetlights on black painted poles and/or dark grey concrete poles are becoming more common.
Aluminum poles are also used but only I've only seen then on municipal arterial roads(with tapered e arm) and expressways (with davit arm)

those sound Nice....the only place we have Davits are on Broadway Avenue entering downtown from the North.
Interstate Lighting has always been Short Truss Arms on Galvanized poles..this setup is starting to enter cities as well.

Cool I've uploaded a few pictures of the different types of streetlights in my Ontario streetlighting gallery here. I believe davits were more common in the 1960s though.

If the city of Tyler, Texas is replacing a bunch of fixtures, maybe you could contact your local power company to see if they have a salvage operation and get some!
I know Georgia Power does....

i might try that...id be good to get one for sure.
given that most of the fixtures they are replacing work just fine,im not sure if those will be left opperating,most likely they will be scrapped when the new lights are up.

My opinion is the brown non-painted rusty poles, with brown streetlights looks very, well........ UGLY! especially with FCO HPS, like seen in Troy Michigan.
-
Do you mean pure steel poles or gavelized steel?
-
I ment the pure steel poles

California has many different light poles. Here is a breakdown of the different styles that are generally used:
The state of California lights are almost exclusively on galvenized steel light poles with unsupported tapered arms ranging from 6' to 30' in length. Older poles before '66 were double guy types, some were painted steel, many are still in use. Luminaires are generally 200w and 310w HPS, with a few remaining 400w and 700w MV and a few LEDs being tested. In current installations GE M-400A3 FCOs are mostly specified.
In northern and central California, a large portion is served by PG&E. PG&E's freestanding poles are generally galvenized steel with steel tapered elliptical arms of 4'-8' in length. Some poles are aluminum. Pole style can vary a lot because many cities in PG&E's area own their street lights. PG&E's own system uses 70w, 100w, 150w, 200w, 250w, and 400w HPS semi cutoff fixtures. Current installed fixtures are GE M-250R2s, M-400R3s (400w only), Cooper OVZs, and Cooper OVXs.
Here in Southern California, there are several utilities, the largest is SCE. SCE has only two pole styles: fluted steel and octangal (sp) concrete. Fluted steel poles are pre '66 and use overhead wiring. Concrete poles use both overhead and underground wiring. Most of the concrete poles have aluminum upsweeps, the reminder use steel upsweeps. 50w, 70w, 100w, 150w, 200w, 250w, and 400w HPS semi and full cutoff lights are used. GE M-250R2s and M-400R3s are currently installed. Other utilities such as LADWP, SDG&E and others are similar to SCE generally but with some variations.

Many municipalities in my state had their streetlights upgraded to HPS as a result many mercury vapor ones have been discarded so they're not too common anymore and my utility company started replacing defective MV streetlights with HPS streetlights in mid 2008. Examples:
175 watt MV=100 watt HPS
250 watt MV=200 watt HPS
400 watt MV=200 watt HPS
1000 watt MV=400 watt HPS
-
Duquesne Light and Allegheny Power both install Cooper Lighting OVZs and OVXs but their wattage configuration is different though for HPS. Allegheny Power replaces defective 175 watt MV streetlights with 100 watt HPS stretlights only, Duquesne Light replaces defective 175 watt MV streetlights with 70 watt HPS and 150 watt HPS streetlights depending on the location and volume of traffic. I have seen defective 400 watt MV streetlights in their area replaced with 250 watt HPS and 400 watt HPS streetlights, even 150 watt HPS. Allegheny Power just replaces defective 250 watt MV and 400 watt MV with 200 watt HPS streetlights.

My electrical company does this...
100 watt MV = 100 watt HPS
175 watt MV = 150 watt HPS
250 watt MV = 250 watt HPS
400 watt MV = 400 watt HPS
1000 watt MV = 1000 watt HPS
crazy eh?!
At first I thought that was like going overkill....because HPS uses more lumens than MV and point of HPS was to use more lumens per watts...
But I thought again...it could be good thing.......that it may be better because if you use more lumens on HPS to make better visibility.....
-
What i observed here:
250W MV -> 150W HPS (but about two decades ago)
2*125W MV -> 150W HPS with group dimming (voltage reduction)
125W MV -> 70W HPS
80W MV -> 58W CFL

I have never seen 1000 watt high pressure sodium used for streetlighting, except at Reliant Energy's plant in Springdale Borough which used to belong to Duquesne Light and they do have it on their lighting tariff for sodium vapor.

That is Very Crazy......but like you said......Brighter to compensate for the Lower Visability of HPS.

Come to Baltimore City...and you'll see 1000 watt HPS used for streetlighting on some of the city roads...
-
does HPS Come in any Wattage higher than 1000?
-
I try to imagine, how it would look. Here the highest wattage for HPS streetlights is 150W and on main roads use a dimmer box reducing their power input down to 100W during the night. But poles are here really very close to each other (compare to what i've seen in US when driviing in Salt Lake City from the airport - but i wasn't there at night),

Pittsburgh has mostly 200 and 250 watt HPS and some 400 watt HPS ones as well.

our Main Streets and Larger Residental Streets are lit with 250 and 200 Watt Sodium as well.
our Residental streets are still mainly 175 Watt MV Nemas with Spot Replacements of 100 Watt HPS.
and Recently with those new lights they have put around Loop 323...those are 400 Watt HPS.
