Basic Differences Between T5, CCFL, EEFL and LED Slim Light
Basic Differences Between T5, CCFL, EEFL and LED Slim Light Boxes
The decision of what type of slim light box to buy can be somewhat confusing if you do not analyze the unique properties that each light box has, and weight these properties against a list of prioritized reasons for which you are purchasing a slim light box. The following is a list of things to consider when purchasing your slim light box.
Aesthetics: Does the look of the slim light box weigh heavy on your purchasing decision? If it does, then the first choice would be that of lamp source. Edlite offer the four lamp source slim light box [LED, EEFL,CCFL, T5] for you choice. Then, beyond choosing lamp source, you should look at the profile of the frame. The newest breakthrough in slim light box technology is the emergence of LED's. By utilizing very small footprint LED lamps, the frame of the slim light box can be reduced down to 0.59 inches thick. This is less than 5／8" thick! This LED slim light box is not even a box: It is a panel! It has a very sleek and thin look when mounted to your wall. If I were purchasing for a high-end department store, this is elegant look I would want to portray.
Electrical Consumption: This is not a consideration one usually puts at the top of the priority list when purchasing light box panels, but believe it or not, it is a very important factor. See chart below.
Who is Going to Change the Bulb? This is a very important consideration that most purchasers don't even think about up front. Do you have a full-time, reliable janitorial or facilities management staff? Will you be shutting down each slim light box at the end of each business day, and turning them back on in the morning? Don't kid yourself, this virtually never happens!
a. Traditional T5 slim light boxes have bulbs that last about 1.5 years if you are leaving the slim light box on 24 hours a day, 7 days a week. When just one of two bulbs dies, a huge cold spot [shadow] appears on your slim light box. Will a janitorial person quickly take notice, have extra T5 bulbs on hand, and come quick for a bulb change-out? Will the box sit idle for days on end, half lit up and half in shadows? The maintenance and bulb change-out is simple, but like mowing your lawn or cleaning your gutters, it can be an annoying and often procrastinated chore. So, if bulb changing is not your thing, don't choose T5 technology
b. CCFL have a more difficult symptom: Their bulbs are very difficult to change because they are very thin and installed into the slim light box frame in an integrate manner. Unless you have a knack for tinkering, or some craftsman-type ability, these light boxes usually need to be returned to the factory for bulb replacement. The good point is that CCFL bulbs will last 4 to 5 years [if leaving the light box on 24 hours per day, 7 days per week]
c. EEFL slim light boxes have a life of about 50,000 hours of life, the bulbs are easy to change, but easy to broken in the delivery.
d. LED slim light boxes have a life of about 100,000 hours of life! For all practical purposes, this light box is going to last and last 100,000 hours divided by 8760 hours per year= 11.41 years]. You will spend a bit more on the upfront purchase, but you will get payback in both convenience and cost-savings from bulb replacement (labor and materials).
