LED Edge Lit Glass Specification Checklist Should Include:

1. Which surface of the glass to be etched (i.e. 1st or 2nd)? Is there a high traffic side of the glass? Frosted glass (if not treated with ClearShield) can be soiled from handling. If there is a side of the glass that is less likely to be touched by others, it is recommended that the glass etchng be on that surface. Surface reflection can wash out the frosted glass surface. The frosted areas of the logo block out the surface reflection which makes the logo easier to view. A frosted glass logo can be enhanced or highlighted with proper lighting such as spotlights or LED lighting.

2. Positive or Negative etch? In most cases, Logo's or graphics with small, fine or intricate detail on clear glass will be greatly enhanced when the background is left clear and the edge lit detail is etched. This is commonly referred to as a positive etch.

3. Surface etch or 3D depth carve? Tempered glass cannot be deep carved safely. If depth is desired in tempered glass, the sandblasting should be executed prior to tempering or use annealed glass that is laminated to meet code requirements. Tempered glass etching can be safely done to a depth not to exceed 1/8 of the total thickness of the glass. This gives a noticeable 3D effect without compromising the integrity of the etched glass.

4. Specifying On-Site Systems as a source in your plans to ensure your glass etching or edge lit sign project will be completed correctly, on time, within budget and in a professional manner.
