Garrett cut the letters out of MDF and covered the front surface with AC ducting/aluminum tape. He bought 4″ diamond plate tape rolls. The tape really helped reflect the lights off the letters.
He used ordinary lighting sockets and 14 gauge wiring to wire it all together. Garrett got the normal, 60W lightbulbs that you can find anywhere.
He used paint thinner on a rag to quickly wash the wattage print off–to give the bulbs a cleaner look. Then he used a separate dimming circuit for every letter so he could light each up independently from the other.
Budget was around $400.
