Thanks Frost. You'd be shocked at how easy it was. PITA and very time consuming, but easy.
Kevin, the savings begins the moment you plug them in. However, complete ROI can vary. In my case, it calculates as follows:
Based on my electrical usage and a 30 day month, my current lighting for my display alone costs $54.60/mo.
The new LED lights w/ cooling fans will cost approximately $16.20/mo for a total savings of $38.40 per month or $460 per year. Based on electrical consumption alone, the ROI would take about 36mos to pay for itself.
HOWEVER, then you factor in the cost to replace bulbs, which in my case runs about $500/yr. Now, depending where you are in your replacement schedule, this will knock the ROI down to 12-18mos. Ideally, you want to do this when you are due for new bulbs which makes ROI closer to 12 mos.
NOW, if you decide to sell your existing equipment, this trims off the cost of the initial investment which shortens the ROI even shorter. In my case, lets say I invested $1500 in LEDs and sold my existing equipment for $750, the ROI would only take 6 mos. After that its a true net savings of $1000/yr in bulbs and electrical.
