The bulbs will total around $50 for all 14.
QUESTION: has anyone gone ahead and done this and noticed a decrease in overall energy usage?

Why not just do the calculation to figure out how much you will save, the math is quite simple?
E.g., On average you save about 50W/bulb with an LED
Assuming you turn the light on for 6 hours per day = 300W/bulb/day =109.5kw/bulb/year
If your hydro cost is $0.10/kw, then you save around $10.95/bulb per year.
Also FYI, tho LED last much longer than incandescent, they don't really last 10 years/50000hr+ like they claim.
My business replaced everything with LED a few years back, they all went out after about 3 years (10-12000 hours)
This was 5years+ back tho, maybe things have improved a lot recently.
