  Title Does ambient light at night reduce total melatonin production? Type Journal Article
  Year 2015 Publication Hormones Abbreviated Journal Hormones  
  Volume Issue Pages  
  Keywords Human Health; melatonin; ambient lighting; indoor light; sleep; *Circadian Rhythm; chronotype  
  Abstract It was with great interest that we read the recent study by Hersh et al on the effects of sleep and light at night on melatonin in adolescents. Of particular interest was their focus on electronic use after “lights out”. The authors highlight the importance of understanding what effects this may have on sleep, citing a survey that showed that 72% of American 13-18 year olds regularly use a cellphone or computer before trying to go to sleep. In their study, Hersh et al1 did not observe a significant suppression in urinary morning melatonin (aMT6s) levels with respect to the use of electronic devices between lights off and sleep onset. Therefore, the authors conclude that “nighttime behaviors of adolescents by and large do not impact urinary melatonin levels”. Absence of evidence, however, is not the same as evidence of absence, and we believe that the authors’ conclusion is premature.

  Title Light-emitting diode street lights reduce last-ditch evasive manoeuvres by moths to bat echolocation calls Type Journal Article
  Year 2015 Publication Royal Society Open Science Abbreviated Journal Roy. Soc. Open Sci.  
  Volume 2 Issue 8 Pages  
  Keywords Animals; artificial lighting; light-emitting diode; street lights; bats; moth predation; Nyctalus  
  Abstract The light-emitting diode (LED) street light market is expanding globally, and it is important to understand how LED lights affect wildlife populations. We compared evasive flight responses of moths to bat echolocation calls experimentally under LED-lit and -unlit conditions. Significantly, fewer moths performed ‘powerdive’ flight manoeuvres in response to bat calls (feeding buzz sequences from Nyctalus spp.) under an LED street light than in the dark. LED street lights reduce the anti-predator behaviour of moths, shifting the balance in favour of their predators, aerial hawking bats.

  Title On-road experiment to assess drivers' detection of roadside targets as a function of headlight system, target placement, and target reflectance Type Journal Article
  Year 2015 Publication Accident; Analysis and Prevention Abbreviated Journal Accid Anal Prev  
  Volume 76 Issue Pages 74-82  
  Keywords security; lighting  
  Abstract Adaptive headlights swivel with steering input to keep the beams on the roadway as drivers negotiate curves. To assess the effects of this feature on driver's visual performance, a field experiment was conducted at night on a rural, unlit, and unlined two-lane road during which 20 adult participant drivers searched a set of 60 targets. High- (n=30) and low- (n=30) reflectance targets were evenly distributed on straight road sections and on the inside or outside of curves. Participants completed three target detection trials: once with adaptive high-intensity discharge (HID) headlights, once with fixed HID headlights, and once with fixed halogen headlights. Results indicated the adaptive HID headlights helped drivers detect targets that were most difficult to see (low reflectance) at the points in curves found by other researchers to be most crucial for successful navigation (inside apex). For targets placed on straight stretches of road or on the outside of curves, the adaptive feature provided no significant improvement in target detection. However, the pattern of results indicate that HID lamps whether fixed or adaptive improved target detection somewhat, suggesting that part of the real world crash reduction measured for this adaptive system (Highway Loss Data Institute (HLDI), 2012a) may be due to the differences in the light source (HID vs. halogen). Depending on the scenario, the estimated benefits to driver response time associated with the tested adaptive (swiveling HID) headlights ranged from 200 to 380ms compared with the fixed headlight systems tested.

  Title Parking lot lighting based upon predictions of scene brightness and personal safety Type Journal Article
  Year 2015 Publication Lighting Research and Technology Abbreviated Journal Lighting Res. & Tech.  
  Volume 49 Issue 3 Pages 293-304  
  Keywords Lightingl Security; parking lots; public perceptions; lighting levels  
  Abstract Providing subjective impressions of security is central to outdoor lighting design. Current parking lot lighting recommendations are based upon photopic illuminances, regardless of spectrum. Scene brightness perception is directly related to impressions of security, and depends upon both light level and spectrum. A provisional model was used to predict scene brightness for three parking lots, each illuminated to different levels by different light sources. Observers judged scene brightness, security and other factors for each lot. The provisional model accurately predicted both scene brightness and security judgements. The lighting associated with the best subjective ratings also had the lowest power density. A design method using ‘brightness illuminance’ is presented, which can lower system costs while maintaining a sense of security by users.
