Neon & LED supply since 1975 The parts that keep signs lit. Neon & LED supply since 1975
CPI Advanced stocks neon transformers and LED lighting in our Chino, California warehouse — supplying sign shops, contractors, and anyone with a neon sign to keep running.
How we work
Stocked, matched, supported.
With limited options available today, finding a reliable source for high-quality electronic neon sign transformers can be challenging.
Many customers spend considerable time searching for trustworthy suppliers for their neon sign needs.
However, as neon continues to have enduring appeal, the demand for innovative fabrication, design, and servicing remains robust.
Fortunately, at CPI Advanced Inc., we are dedicated to enhancing our top-notch design, quality, and exceptional service to meet the needs of our valued customers.
Your satisfaction is our priority, and we are committed to helping "Keep Neon Alive."
We stock it
Inventory sits in our own warehouse in Chino, so an order is a shipping question, not a lead-time question.
We match it
Tell us the sign and we will tell you the supply that fits it. A transformer sized wrong is a transformer you buy twice.
We answer
Fifty years of neon and LED questions have come across this counter. Yours is probably not a new one.
