LED Lighting in Industrial Situations

LED lamps, if they are properly cooled and rated for their task will last for their 50,000 to 100,000 hours and use less power. Fluorescent lamps are good for less than half that. So if they must be changed 3-4 times and use more power a life equation can be solved incorporating these costs.

Here is one for flourescents, if will serve for LEDS as well, just change the values. You may also find an LED one, but they are made by LED makers and have a bias

flourescent costing

This company does not have a flood light and there bulbs are not due for sale until the end of this year but they are worth checking out for superior light output upfront cost and life span.

Contact one of the potential suppliers and have them set up a demonstration in one of your existing buildings. Presented together with a written estimate of the operating cost savings, a spiel about showing the company has green credentials, and an assessment of the PR value to the company, that should convince the bean counters. The other detractors will usually follow the money.

The trend to newly developed devices may be attractive shows but may not be fully alternate to Natural light spectrum [Sunlight].

IIncandescent bulbs are the nearest approach so far but not a good conversion one and life due to which an economical one is preferred, but the drawbacks in damaging eyesight and definition is generally ignored.

Led lighting in the commercial field has come a long way. One good source of info is pathway lighting (http://www.pathwaylighting.com/). They have wide variety of led lighting options and knowledgeable staff to help answer any of your questions since they sell both florescent and led lighting packages.

I have not checked out LED lighting lately, but two things to consider in your application: 1. If you're using conventional ballast, watch out for stroboscopic effect with moving machinery. Rare but dangerous. No such problem with LEDs! 2. You might want to consider metal halide lamps as part of your proposal (with electronic ballast), but restriking time could be a problem. 3. LED luminaries can be quite innovative and direct light in ways that conventional luminaries may struggle to achieve. It can assistbin reducing glare, for example. And I like the other ideas mentioned too, future-proofing your installation, life-cycle cost comparison, etc.
