The decision of what
type of 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 light
box. The following is a list of things to consider when purchasing your
light box.
- Aesthetics:
Does the look of the light box weigh heavy on your purchasing decision?
If it does, then the first choice would be that of color - "black"
or "satin silver". Displays2go offers the convenience of stocking
all three models [LED, CCFL, T5] in both options. Then, beyond choosing
color, you should look at the profile of the frame. The newest breakthrough
in light box technology is the emergence of LED's. By utilizing very
small footprint LED lamps, the frame of the light box can be reduced
down to .83 inches thick. This is less than 1" thick! This LED
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. See
profile differences below:
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. It is a fact that in Israel, there has been
a mandate for airports to replace all existing, previously installed
T5 and T8 light box panels with LED based light boxes. Because of this,
light box manufacturers and suppliers are scrambling to source and bid
on over 1500 new LED light boxes that need to be installed. The premise
of this directive is primarily based on electrical savings. If you look
at the power consumption of a traditional T5 light box, and compare
it to either CCFL or LED light boxes, you will quickly see that there
is "payoff" to be had over the years due to electrical savings.
See this comparison chart of electrical savings for a typical, 24"
x 36" sized light box. Some institutions may even have several
light boxes installed throughout their facility or retail environment.
Multiply these savings by many installed light boxes and the math becomes
easy: CCFL is best, closely followed by LED. T5 lamps burn the money.
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 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!
Traditional T5 light boxes have bulbs that last about 1.5 years if you
are leaving the 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 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.
CCFL have a more
difficult symptom: Their bulbs are very difficult to change because
they are very thin and installed into the 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]. Believe it or not, for smaller light panels - less than 27"
x 41" - many customers can justify the cost/benefit after about
5 years; they will just reorder a new light box when their old CCFL
light box starts to deteriorate. This is one reason why we only offer
CCFL light boxes in smaller footprints [sizes up to 27" x 41"].
Larger footprints tend to become more permanent fixtures, installed
into walls at airports and so-forth. Un-mounting the light box to change
the bulb, or to return the entire light box back to the factory, can
be a huge burden. We personally are willing to change the light bulb
if it is returned to our factory, but then your have to deal with UN-mounting
the fixture, looking at an eyesore on the wall during shipping time,
and trying to find packaging necessary to return the light box to the
factory unharmed. For smaller sized menu board and display stand applications,
however, the CCFL lamp can be a good choice - especially when you can
justify replacing the light box after 5 years. Also, the price of the
light box 5 years from now will probably be a fraction of today's cost.
LED 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].
Brightness:
We have designed and specified all of our light boxes to be of good
quality brightness. This means that they will all have an above average
LUX, which is the measurement for brightness. We see many competitors
selling "sub-par" light boxes, which when turned on have minimal
LUX or brightness. In very general terms, a light box should have the
following LUX measurements:
- Excellent, Very
Bright: above 2000 LUX
- Very Good, Good
Brightness: between 1750 and 2000 LUX
- Basic Brightness:
between 1600 and 1750 LUX
- Unacceptable
Brightness: below 1600 LUX
We are talking about
average brightness throughout the light panel. Our light boxes have
technology designed to transfer the brightest light, which initially
occurs next to the light bulb located at the edge of the panel, to the
center of the light box. This is opposite of logic! How can a light
box be brighter in the middle, away from the light bulbs that are positioned
on the edge? It is through specially engraved or printed patterns in
the sub-acrylic back panel that channel the light in this desired manner.
- If you want brightness,
if you want the ultimate impression, than T5 light boxes are the best.
They are, without a doubt, the strongest in brightness, often measuring
in excess of 3500 LUX! You do, however, pay for this brightness in
additional wattage and electrical consumption. But these T5's are
bright!
- Both CCFL and
LED have similar LUX readings at applicable sizes. The CCFL often
measures a bit better than the LED, but to the naked eye, this would
not be noticeable. Only when measured with a light meter.
- Budget:
A very tricky question to answer: "apparent budget" or "true
budget"? "Apparent budget" refers to the initial purchase
price, while "true budget" reflects the true cost after factoring
in electrical consumption and the cost of bulb replacements.
- T5 light boxes
are the cheapest; they have the lowest "apparent budget",
but can easily cost more then the most expensive LED light box after
4 to 5 years of use.
- CCFL light
boxes are in the range of the T5 with "apparent budget",
only costing slightly more than T5's. Electrical consumption savings,
however, will soon pay for this difference. After just one year,
the electrical savings with a CCFL box will be more than the initial
cost difference between the T5 and CCFL box
- LED light boxes
are by far the most expensive for "apparent budget", but
this premium can quickly be justified [money saved from operating]
over a few years. Adding together the combination of electrical
efficiency [very good], bulbs that last forever [11 years], and
sleek profile, it often benefits to "pay-up" and invest
more today on the initial purchase.
- Environment:
All fluorescent bulbs (CCFL & T5), from tubes to compacts, contain
a small amount of mercury vapor to create the light. Intact bulbs are
not considered hazardous, but when thrown away, the bulbs get crushed
and the mercury is released. Though it is a small amount of mercury
that would not harm you on an occasional basis many countries have deemed
the bulbs hazardous waste. Agencies such as the European Waste Catalogue
(EWC), Environment Agency in the UK, and the Environmental Protection
Agency (EPA) in the US have guidelines for disposing of these lamps.
The EWC for example, requires that hazardous and non-hazardous waste
be disposed of in separate landfills. Most agencies advocate that fluorescent
lamps should be sent for recycling as a way of better managing the waste.
Companies such as SustainaLite (www.sustainalie.co.uk) list organizations
on their website that provide recycling services and in the US most
state or city websites provide information. The once acceptable practice
of throwing them away is no longer acceptable and users of fluorescent
lamps have "Duty of Care" to dispose of lamps properly. While
rules and regulations for disposal vary, during the life of the bulb
practicing energy conservation techniques is always encouraged. Fluorescent
bulbs offer great environmental advantages in that they convert electricity
into illumination three to five times as efficiently as incandescent
lights thus using less energy and lamp life is longer.
