Had a customer send this to us by email, maybe they'll chime in a tell us more but... It's simple, they're replacing cheap plastic LED power supplies made in CHINA with better quality, better thermal cooling LED Power Supplies...OUR Union Korean Made LED Power Supplies. Our 60 watt (displayed above) is IP68, Recognized by UL as Class II (SAM) and for Wet Location. These are versatile, you can use in a box or sign structure, or use externally. Most importantly you can breath easy when your UL Inspector surprises you with a visit and sees these units, including our 120watt version which is one of the few approved and listed in the SAM The cheap plastic Chinese LED Power Supplies by Principal LED & others are great for areas that have good cooling like external fans or for your kids school science projects but not in closed areas where ventilation is not great. The "cheapies" are attractive for the price at $12 or less, but not great for consumers who have to pay the service bill of a crane and labor to replace because as professionals we know these only last for short periods of time. "Buy the best and only cry once"

So I came across this over the weekend on Sloan LED's Sign Box II and thought I'd post here for anyone interested to kick it around on their spare time. I didn't even have to do much on this one myself but one thing I did see on the Fluorescent side of things is a lot of fumbling around for something that is pretty simple with the simplest kind of knockdown raceway that anyone can just about pick up from their local hardware stores these days. I thought I would finish, or tell the rest of the story not mentioned, and that's what our expected cost would be using one over the other to save in time and what our customer will expect to pay for it. The Time Elapsed Video The final product with time Let's break this down on cost, and cost of operation and take a look at what we just saw and how it relates to our cost, what we will have to sell it for, and what the consumer will have to pay for. Let's just call this a 6' x 5' double sided cabinet.

How much would you sell that 6'x5' (30sq') double sided cabinet for with simple faces (White with black lettering) as a Fluorescent and as a Sloan LED's SignBox II System fabrication & installation? What will your profit margin be? As a sign shop are we making money paying for and using a higher cost system? In the amount of time it takes to fabricate a complete sign cabinet are we loosing out on money keeping it conventional which has the lower cost and more proprietary (custom)? Now slightly away from this subject an in another subject to think about. What's to keep our trade to becoming as a commodity where the consumer can just go to HomeDepot and put their own LED system in where they just peel and stick? Now a day even schools have wide format printers, so vinyl and printing aren't really apart of the sign trade anymore. The only thing that's left IMO is sign painting, conventional back-lighting and Neon. When it comes to a mom & pop store sign just about anyone now a day can keep up a sheet of plex, anyone can print film, and just about anyone can pick up LEDs from a lighting store. What will keep our industry as a trade and be turned into a commodity which is the direction being pushed by those outside of our trade ? Large sign programs? Are we killing our own trade by not building unique and proprietary signs that does save money for us and the consumer? just some thoughts I'd throw out there since so many light source manufacturers are trying to dictate to the sign shop labor and cost and what they should be charging for retrofits like Ventex markets Are we soon to be just the middleman, the means for manufacturers to sell their products
