NEMA’s Electroindustry Business Conditions Index (EBCI) for current conditions in North America measured 58.3 in November as a larger share of panelists reported conditions improved (33%) than reported they deteriorated (17%). The November EBCI reading was a substantial increase from the 44.7 recorded in October.

In contrast, the EBCI for future North American conditions fell to 55.6 in November, down from 68.4 in October.

construction2The U.S. Census Bureau of the Department of Commerce recently announced that construction spending during October 2015 was estimated at a seasonally adjusted annual rate of $1,107.4 billion, 1% (±1.8%) above the revised September estimate of $1,096.6 billion. This figure is 13% (±2.5%) above the October 2014 estimate of $979.6 billion.

During the first 10 months of 2015, construction spending amounted to $888.1 billion, 10.7% (±1.3%) above the $802.3 billion for the same period in 2014.

Spending on private construction was at a seasonally adjusted annual rate of $802.4 billion, 0.8% (±1.0%) above the revised September estimate of $795.8 billion. Residential construction was at a seasonally adjusted annual rate of $399 billion in October, 1% (±1.3%) above the revised September estimate of $395 billion. Nonresidential construction was at a seasonally adjusted annual rate of $403.4 billion in October, 0.6% (±1%) above the revised estimate of $400.8 billion.

In October, the estimated seasonally adjusted annual rate of public construction spending was $304.9 billion, 1.4% (±3%) above the revised September estimate of $300.8 billion.

CIE, the global lighting organization that maintains the CRI standard, is now studying TM-30:

The CIE recognizes that the colour fidelity metrics including the CRI do not assess other important aspects of the colour qualities of light sources, in particular, those related to colour preference. CIE TC 1-91 is developing a Technical Report on this subject, which will be the groundwork for developing colour preference metric(s).

The CIE encourages further research on these two aspects of colour quality, which may be useful inputs to the current or future work of CIE. In particular, the CIE supports the study of the recently published IES[1] Technical Memorandum TM-30, to which some CIE TC 1-90 members have contributed. This work was recently proposed for consideration in TC 1-90, which voted to make its Rf metric the basis for the TC’s first working draft.

The CIE also recommends that important lighting metrics such as the Colour Rendering Index require formal international agreement. New metrics introduced at the regional level could cause confusion in the global lighting market.

The process of developing CIE recommendations by scientific consensus often requires considerable time. However, the CIE is expediting the work of TC 1-90 and TC 1-91 and they both plan to complete their Technical Reports within 2016. The CRI is widely used in many regulations and specifications, therefore an orderly transition is needed when a new metric is to be introduced. For this reason the current CRI (CIE 13.3) will not be officially replaced until a new metric is widely accepted.

gigahertzGigahertz-Optik’s hand-held, spectrometer-based Photosynthetically Active Radiation (PAR) meter provides PAR, illuminance, color and spectral data to fully analyze any type natural and electric light source, including SSL/LEDs employed in plant growth applications.

The BTS256-PAR measures PAR PPFD (µmol/(m²s), R/FR red to far red irradiance ratio, DLI daily light integral (time resolved with data logger) and DIN ASY1, ASY2, ATP1, ATP2 irradiances. A unique feature of the BTS256-PAR is that five UWF user specified spectral weighting functions can be self-programmed into the meter. The meter also measures photopic and scotopic illuminance, S/P ratio, EVE factor, irradiance and spectral irradiance, color coordinates (x,y and u’v’), color temperature, deltaUV, CRI, CQS, color purity and spectral irradiance.

Other high-end features normally found in only laboratory level instruments include a built-in electro-optical shutter for dark-signal compensation that increases the highly linear dynamic range of the C-MOS diode array detector.
 
A large area diffuser provides a precise cosine corrected measurement geometry (f2<3%), a basic requirement for accurate illuminance measurements. This is especially important when measuring oblique angle full immersion light as in a greenhouse and daylight illumination.
 
For use without PC, the BTS256-PAR is powered by a rechargeable lithium battery and features a large size transflective display located on the same side of the housing as the input optic. Three front panel control buttons control all meter functions.
 
For full PC control, storing data and to recharge its battery a USB2 interface is standard equipment.
 
The supplied S-BTS256-E software controls all functions necessary for measurement, display and data export. The software offers different routines for data acquisition, selectable numerical and graphical displays and different file type export options.
 
SDK software development kits are available for self-programmers to embed the BTS256-PAR within their own software.
