Germination heat suggestions!

I germinate my plants in my shop where the average winter temp is around sixty five degrees F. My tomatoes always germinate and grow well under my fluorescent grow lights, but my pepper plants have always struggled to germinate and grow in the same conditions. This year, I plan to add some additional heat to help the peppers germinate and grow.

I've thought of many different methods. Since I germinate on a raised tray about two inches below the lights and then lower the tray as the plants grow, I've considered using a heat lamp to heat the enclosed space below the tray removing the lamp after germination is complete. I can incorporate a thermostat into the setup to moderate the temp at around eighty degrees. I've also considered simply using heat mats below each germination tray. I haven't really decided what I want to do.

Suggestions will be appreciated along with recommended equipment and vendors who sell it online.
