Don't take my word for it....Rowan University did a case study on it and showed a 6 month payback or ROI. The bulbs last about 10 years so your savings will be over 9.5 years. Invest about $9/bulb for 3 bulbs or approximately $27 to save approximately $5/month or $60/year per sign and over 10 years you have saved $600 per exit sign. Of course if you order in bulk you will save even more! Depending on how many exit signs with three bulbs in them are located at your business the savings can add up fast.
