The "Great Loss" to the Nob Hill Neighborhood was the installation of LED Lights.  This has led to the loss of seeing more wildlife at night.  This has led to the loss of the "Warm And Cozy Feel" Nob Hill Historic District had when we had the Old Sodium Street Lights.  This has led to the Loss of Jobs For PNM Workers in ABQ, NM since the LED Street Lights have been outsourced to another company outside of the United States.  This has been "The One Great Loss" to Nob Hill and the Historic District since I have lived here in Albuquerque, NM owning a home in Nob Hill Historic District.

Advantages:
- Very efficient lamp
- Powerful lamp for use of large areas
- Despite a warm up time of 5-10 minutes it restarts immediately if there is a brownout
- Lumen output does not drop with age (such as in LEDs or incandescents)

Disadvantages:
- Worst color rendering of any lamp

- Sodium is a hazardous material which can combust when exposed to air (such as if the bulb is broken in the trash)

I especially like how the Lumen Output does not drop with age (like in LED Street Lights) that have replaced them.  I tried very hard to stop this from happening and am still disappointed at how I was greatly overruled.

Advantages:
-Energy efficient source of light for short distances and small areas. The typical LED requires only 30-60 milliwatts to operate
-Durable and shockproof unlike glass bulb lamp types
-Directional nature is useful for some applications like reducing stray light pollution on streetlights

Disadvantages:
-May be unreliable in outside applications with great variations in summer/winter temperatures, more work is being done now to solve this problem
-Semiconductors are sensitive to being damaged by heat, so large heat sinks must be employed to keep powerful arrays cool, sometimes a fan is required. This adds to cost and a fan greatly reduces the energy efficient advantage of LEDs, it is also prone to failure which leads to unit failure
-Circuit board solder and thin copper connections crack when flexed and cause sections of arrays to go out
-Rare earth metals used in LEDs are subject to price control monopolies by certain nations 

-Reduced lumen output over time

I especially am disappointed that LED Street Lights use Rare Earth Materials that can cause damage to Mother Earth through the Use of Strip Mining in other countries.

This hopefully will be our future solution that will replace the LED Lights at least in the Nob Hill Historic District Neighborhood.  I am a great fan of less light at night and one can always carry a personal flashlight if they want more light while they are out walking at night.

Recent Nob Hill Neighborhood Newsletters have reported on architecture students scouring Nob Hill for a course at UNM School of Architecture + Planning.

Professor Steven Moffson, who also works at NM Historic Preservation Division, assigned them the research to determine if a neighborhood qualifies for listing as a historic district in the State and National Registers of Historic Places.

He kicked off the process with a community meeting last May. Students then collected reams of data for a Multiple Property Documentation Form. This is a big job and a great favor to Nob Hilleños as it would otherwise be very costly.  Steven presented results to the community in an October 12 zoom meeting, reporting that the 1925 Granada Heights and 1945 Broadmoor Addition have been found to qualify for listing. The community can now explore the next steps in adding one or both neighborhoods to the registers. The 1916 University Heights was studied but needs additional work due to its size.

Steven notes that listing is “all carrot and no stick”. It is a distinction denoting a district that has been professionally evaluated and found worthy of preservation. It does not restrict owners from doing what they wish with their property inside or out. It raises awareness and often inspires property owners to be good stewards, maintaining the architectural principles of the original development, particularly on the outside of the house.  A nomination identifies contributing properties, houses that retain their historic character. If a district is listed in the NM Register owners of contributing properties can claim New Mexico tax credits for qualifying pre-approved renovation and can purchase a plaque noting their house’s contribution.

Prof. Moffson will soon post details in an ad in the Albuquerque Journal and plans to post the nominations on http://www.nmhistoricpreservation.org/ the first week of January.

He and staff of the NM Historic Preservation Division will then host a public information meeting being scheduled for about 2 weeks after the nomination forms are posted.

These activities will be announced on the Nob Hill email list at www.NobHill-NM.com and on the events calendar there.
