Letty, thank you for the comment. Induction lamps and ballast are available in 40 - 400W. A dramatic reduction in our energy consumption would decrease our dependency on foreign resources no matter where the fixture in whole or in part is manufactured. An Induction parking garage fixture will cost approx. $200- $250 and outlast an HID 4 times.

Induction fixtures have come down in cost.

I have a case study i would like to share with you regarding Induction street lighting. As you might know photometrics are exactly that photopic, this fails to take in consideration scotopic light which Induction lighting has an advantage.

While some of the arguments in this article for induction lighting are sound (yes, they claim 100,000 hours as opposed to other lamp sources), keep in mind that the two mainstream suppliers of these sources - Sylvania and Philips - are limited in their wattage options as opposed to other sources. Sylvania's Icetron system only goes up to 150W and Philips is 165W. From a LIGHTING perspective, you certainly cannot replace the output of a 400W Metal Halide with a 150W Induction system in a standard parking garage fixture. You'd need multiple fixtures to achieve the same footcandle levels, and the upfront cost is prohibitive from traditional sources - a typical MH parking garage fixture can run about $150 (Price to the Distributor) vs. about $450 for an induction fixture (the lamp/generator replacement cost to a manufacturer alone is $200). There are also few lighting fixture manufacturers who design around Induction sources, as they require unique housings and reflectors to guarantee maximum light output due to their unique shape (elongated doughnut shape and oversized A lamp, respectively).

Your quote about Induction lighting (and other sources including CFLs and LEDs) reducing our dependence on foreign resources is also questionable, as these sources are manufactured in Mexico, China, etc. - not locally in the US. It would be nice to believe these sources are still made on domestic soil, but sadly that is no longer the case.

There is a place for induction lighting - roadway applications, freezers, etc. but be cautious from a lighting perspective in how these sources perform photometrically for a given application, how easy they are to obtain for replacement (they aren't a normal stocking item on a distributor's shelf), the costs associated with these sources, and how "green" they really are.

I review the possibility to replace our HID lamp for several plants in Indonesia. However, this project will only feasible if it can generate a tangible saving within 4 years operation time(self funding projects). Unfortunately I can't get any supportting information about it. I hope I can find a real fair comparation (both technically, economically, market availibility and spare parts) among induction lamps, fluorenscen and HID. Can you help me?
