Take the Streetlight Survey

PAR members may want to take this survey on proposed SF streetlights:

Hi everyone,

Last week, one of the folks on the SF Smart Lighting mailing list brought this survey on decorative street lights to my attention: 
http://www.surveymonkey.com/SFStreetlights 

By way of helping to provide information regarding the comparative light pollution aspects of the fixtures being considered, I decided to write up some commentary that may be useful for you in taking the survey.

- Fixture Alternate A
- Lamp Type: High-pressure sodium
This is a typical 'acorn' type fixture.  Although the lamp is likely recessed into the opaque cap, the prismatic bowl does allow some uplight.  With low mounting heights and/or high luminance lamps, these can be quite glary.  The use of HPS, at 2100K CCT, helps decrease the perception of glare however, compared to other lamp types.  Here in S.F. these types of fixtures are usually installed 'bare' without a shade or 'hat' to limit glare and uplight.  By contrast, Honolulu uses the 'hatted' version of this design to reduce glare and stray uplight.  Take a look at the street view on Google maps of Kalakaua Ave. and Kuhio Ave. in Waikiki to see examples.

- Fixture Alternate B
- Lamp Type: High-pressure sodium
Very poor, light polluting design.  It permits significant amounts of uplight and glare for no reason.

- Fixture Alternate C
- Lamp Type: High-pressure sodium
I call this fixture 'the glass salad bowl'.  Similarly to alternative A, this fixture is not fully shielded and thus does produce uplight, and does present glare.  Not my favorite.

- Fixture Alternate D 
- Lamp Type: High-pressure sodium
Similar concerns to alternate B, this light produces significant uplight through its prismatic reflector and apparently translucent top.  And of course is very glary.  Very poor design.

- Fixture Alternate E
- Lamp Type: High-pressure sodium
Similar factors apply as with alternate A, above.

- Fixture Alternate F
- Lamp Type: LED
This is a modern fully-shielded fixture.  Reasonably good glare control, and when installed correctly with the LED array horizontal, virtually no uplight.  As noted before, it is most preferable to use LED's with minimal blue output.  Color temperatures in the 2700K - 3500K range minimize blue light output while still producing a natural looking white light.  Alas, I don't think this fixture is available yet with such warm-white color LED's.

- Fixture Alternate 1
- Lamp Type: LED
The sketch doesn't clearly indicate the optics involved.  Such a design in which the glass lens is simply a clear bowl (not prismatic or textured, and preferably with antireflective coatings) do well in terms of minimizing uplight -- assuming, that is, that the LED array is recessed in an opaque top.  I believe several manufacturers are also offering a similar design, but with a flat lens rather than a clear bowl.  A flat lens is even better from the point of view of uplight control.

- Fixture Alternate 2
- Lamp Type: Ceramic metal halide
This is an excellent fixture from the point of view of uplight.  It is fully shielded with a flat lens and with the recessed lamp probably also controls glare pretty well.  Metal halide is not my favorite source, as it tends to be rather high CCT.  Similar fixtures are available with LED's.

- Fixture Alternate 3
- Lamp Type: LED
Also an excellent fixture from the point of view of uplight.  It is fully shielded and appears that it would provide quite good glare control.  Same issues regarding minimizing blue light emissions from LED's as fixture F, above.

- Fixture Alternate 4
- Lamp Type: LED
       --and--
- Fixture Alternate 5
- Lamp Type: LED
Also excellent fixtures from the point of view of uplight.  They are fully shielded and probably have good glare control.  Same issues regarding minimizing blue light emissions from LED's as fixture F, above.

- Fixture Alternate 6
- Lamp Type: LED
I haven't seen a design like this before, so it's hard to guess how well it does in terns of uplight and glare.  I'd really want to know the BUG score numbers on this one before giving it an endorsement.

- Fixture Alternate 7
- Lamp Type: LED
Looks pretty good as far as uplight.  Fully shielded and probably has good glare control.  Same issues regarding minimizing blue light emissions from LED's as all LED fixtures in survey.  The one thing that concerns me here is that it looks like a lot of the light is hitting the support arms, which is not only wasted light but also is then be scattered upward.  Granted it's a minor point but something to note.


Thanks,
-DG

Thanks for joining us at Sunday Streets!   We had so much fun in Golden Gate Park and along the Great Highway! There we so many highlights to the day, it's hard to know where to even begin! What were your favorite moments?  Share your photos, videos and stories on our facebook page:     The San Francisco Rock Project came out and performed on the Great Highway and were AMAZING!!! They will be back at the August 14th event, so don't miss them!! Photo by Frank Chan      Spotlight on Our Pet Programs:                                   Every month, Shelah Barr donates her time to Sunday Streets by  organizing all of the pet programs that come out. Each month,  she brings out all kinds of folks who dedicate their lives to helping  out our furry friends. Here are some words from Shelah on the work she does, and how she gives back to the community:     "Happy Hounds Massage started as a desire to do for our pets what I was doing for humans – helping them achieve efficient and comfortable movement through bodywork and massage.  I specialize in rehabilitative and therapeutic work, because that’s what my training is in (for humans, and it translates well into work with animals). The majority of pets I see through Happy Hounds Massage are seniors, injured, highly active and permanently disabled - not necessarily in that order.  I work with all small animals but specialize in dogs because they’re like the rugby players of the domestic animal world. They throw themselves into whatever they’re doing with no sense of self-preservation, bang themselves up, then go back for more.  A cat or a lizard for example won’t usually do that – they’ll pretty much just rest when they need to.   I try to support the animal community as much as possible. I’m expanding my social network through Facebook and Twitter as a way to share information about what’s happening in the pet world. I donate Happy Hounds Massage Gift Coupons whenever I can to help organizations raise money, and attend as many of the fundraising events as possible. I started organizing the Pet Program at Sunday Streets because I thought it would be a great way to introduce the local rescues and a public that might normally never meet.  My idea was that it would give the rescues a bigger pool of potential adopters, fosters, volunteers and supporters, and the public would have new opportunities to get involved, be helpful, and learn about personal and social animal care."   Highlight on a Rescue Copper’s Dream is new to the Sunday Streets Pet Program.  It was founded by a local woman, Jennifer Wang, who like so many of us would like to see the end of pet overpopulation and euthanasia. Copper’s Dream rescues dogs and cats of all ages, breeds and sizes, and has North and South Bay chapters. They brought a good variety of dogs and had a pretty successful first day with us.   Pet Photography by Mark Rogers    Mark Rogers is a San Francisco pet photographer specializing in candid, intimate portraits of pets and their people throughout the Bay Area. The above images were taken by him, as well as the volunteer photo on the right. Sunday Streets Raffle!   We are having a season long raffle!

Tonight June 9---ramp closure

Overnight Closure of Southbound Hwy 101/Doyle Drive to Southbound Hwy 1 Thursday, June 9 at 11:00 p.m. – Friday, June 10 at 5:00 a.m. Beginning Thursday, June 9 at 11:00 p.m. through Friday, June 10 at 5:00 a.m. the ramp from southbound Highway 101/Doyle Drive to southbound Highway 1/Park Presidio Boulevard will be closed. The ramp closure is necessary to realign the temporary barrier (k-rail) along the off-ramp to southbound Hwy 1 in anticipation of restoring this exit to two lanes in late June. Closure times were selected due to the expected low volume of traffic. Motorists should use caution in construction zones. Optional trips should be avoided during this closure. See the advisory for a map with detour routes. All dates are subject to change due to weather and unforseen conditions. Please visitwww.PresidioParkway.org for the most up-to-date information.
