LEDs are used in all reverse-lit channel letters that we produce. We primarily use AVL Samsung LEDs in every reverse-lit channel letter unless your branding guidelines dictate otherwise. We have done extensive testing on this brand, including leaving them in a freezing bucket of water for 6 months. We have found this brand to be the pinnacle of LED technology and we strongly recommend it’s use in all of our internally illuminated signage products.
LEDs come in a variety of colors. For white LEDs (used in 90% of our signs) we primarily use 6500k for the color temperature. We have found this to be the best color temperature for internal sign lighting that really makes your graphics pop on your reverse-lit channel letters.
If you want your letters to reverse light another color, we can achieve the look you are after by using different color LEDs or adding a vinyl film to the clear Lexan that is on the back of the letter. We can also mix and match to really hone in on the color that is consistent with your brand.
