Looking for Feedback - Cabinet Signs

[manuellynch]

We do quite a bit of work outside the USA in lighting cabinet signs or light boxes.

We are starting to roll out our systems in the USA.

This is how we help customers estimate the amount of light they need.

Can we get some feedback

Does anyone do light boxes with LEDs in USA?

I know Federal Heath and Blair do.

Contractor I bend glass for had a spec job for Best Buy to re-retrofit a few stores in our area from Fluorescent lamps to LED's. The problem was the cost factor and the rate of return on the investment to save money and maintenance cost.

The cabinets were not the usual small 4 x 8 styles. These were quite large of about 12 x 6 and up. The initial quote was too much for the stores to do it at this time.

Another job was looking at using LED's to replace Metal halides in a few high rise signs situated near the highway. I was shown a product that look something out of a sci-fi movie with LED's all over. The claim was that it would be brighter and (of course) last 10 years with no replacement cost and save money on operating costs. Problem there was cost again. 5 times what a typical re-lamping would cost and no guarantees that it would last or not have any issues..I do not know the manufacture at the time because it was only shown to me bu the contractor. Funny thing is they couldn't get it lit to show me how bright it was supposed to be.

I really don't think LED's have caught on in sign cabinets as of yet...Cost seems to be the factor around here as well as how well they put out light compared to fluorescence tubes. Maybe smaller compact sign cabinets would be ideal but the larger ones are still using HO lamps.
