I have been looking at LED replacement bulbs for church, and there are ones that will replace both T8, T10 and T12 bulbs with the same LED bulb. Would suggest getting the ones that you remove the ballast from the circuit as the ballast is still prone to failure and draw current as they are not 100% efficient. The LED bulbs come in different K ratings of the color spectrum, so that is another consideration. From the literature 2 LED bulbs will put our as much light as 4 40W bulbs(160+Watts) vs 2 LED 18W bulbs(36Watts total) and no loss from the ballast. The bulbs have an average life span of 18+years a 8 hours a day 365 days a year.
