2026-10-28Remote Neon Transformer Placement: Safe Distance from the Tube
Mount the transformer too far and you lose voltage; too close and heat ages the tube. I size the HV lead run and vent the box.

2026-10-28Retrofitting Old Glass Neon to LED Flex: What Transfers and What Does Not
Clients love the cost saving, but a glass-neon retrofit is not a like-for-like swap. The transformer, mounting and even the viewing distance change.

2026-10-28Neon Tube Standoff Spacing: How Far Is Too Far from the Back Panel?
Space the standoffs too wide and long tubes vibrate and crack; too close and the back panel glow washes out. Here is the range I use.

2026-10-28The Real Minimum Bend Radius for Neon Tubing (and Why Forcing It Kills the Sign)
Every neon tube datasheet prints a bend radius. The field reality is tighter, and forcing the bend shows up as a dark spot a year later.

2026-10-28Recolouring an Existing Neon Sign: Can You Match the Original Tube Hue?
When a client wants an existing sign recoloured, matching the original tube is half art, half voltage. I walk through what is achievable.

2026-10-28Mounting Neon Tubing on an Outdoor Facade: What the Spec Sheet Leaves Out
I've stripped and rehung enough facade neon to know the standoff spacing and cabling details that decide whether a sign survives two winters.
