The new color tone is based on spectrally enhanced lighting, which is endorsed by the DOE as an excellent way to reduce energy, carbon footprint, etc. — Provide weblinks to the DOE. • If anybody does not like the new lighting initially, please keep it to yourself. • If anybody does not like the new lighting after two or three weeks, please let me know. It is also important for the installers to finish rooms before the regular workers come for the next day’s work because having two color tones in one space does not look good.

In 2014 and beyond, LED and CMH will get better, while induction and fluorescent will stay about the same. (A footnote is that while writing this, I received another email from an unknown Chinese induction manufacturer. ) 43 Lighting & Controls: Transitioning to the Future Table 8-1 44 Chapter 9 Electronically Ballasted CMH INTRODUCTION Everybody knows about LED, and some people mistakenly consider induction good, but many people do not know how good electronically ballasted ceramic metal halide (CMH) really is.

Philips also has the AllStart CMH lamp, which is designed to work with probe and pulse start magnetic ballasts. These lamps save energy, improve CRI, and have longer life than standard MH lamps. Installed costs are relatively low because there is no Electronically Ballasted CMH 47 new ballast to buy and install, but there is not as much electrical reduction when keeping a magnetic ballast than when using an electronic ballast. Most LED hibay and exterior fixtures have only about 70 CRI. Where CRI is really important, such as with big box stores and car dealerships, 90+ CRI CMH can make colors and textures look better, which can make the merchandise more sellable.
