Why Have LED Wall Pack, When It Comes To Exterior Lighting?
You could have several options in outdoor light fixtures, when it comes to illuminating the exterior of your industrial, commercial or residential premise but rest assured, none of those can match your expectations in reality. This is because the LED lighting experts and designers have come up with LED wall pack in more than one design to suit your individual needs. You could choose from a wide range of wall packs such as -- forward-throw wall pack, semi cut-off, full cut-off, and rotatable wall pack -- and all of it to come at reasonable prices, without compromising on quality or savings in energy by any means.
In this blog, the major types of LED wall packs are highlighted, considering the pattern of light distribution an essential tool for choosing a wall pack. But even before you can get to that, let’s just understand the basic difference between the most commonly used wall packs until date -- the metal-halides, or high-pressure sodium wall packs.
So, let’s consider the second part first.
LED Wall Pack -- How It Differs From Conventional (Metal-Halides or HPS) Wall Packs
Too Long To Get Turned On
One of the basic reasons why metal-halide wall packs take too long to get turned On is -- the technology they work on requires warming up to reach the operating temperature and this process gets too long -- about 15-20 minutes. So, these lights just keep you waiting before you can actually access the light. This is fortunately not the case with LED wall packs as these work on semi-conductor technology.
Expensive To Maintain
The metal-halides at the most last for 20,000 hours within which time, you may need to change the lamps atleast 2-3 times (which means relamping cost). And, this is because with longer hours of use, they become less efficient by losing out on their lumens. This means, in order for them to last for atleast 20,000 hours, you will need a lot of maintenance and higher your maintenance cost. LED wall pack needs to be changed only after it has completed its full lifespan.
The metal-halide wall packs are known or emitting light in 360 degree -- which means in all directions. So, a reflector was needed to direct the light beam towards the intended area. Unless you used it, there was an undue waste of light. If you used it, the cost of the reflector got added to the cost of the light fixture. So, even if you thought, this was less expensive than the current-day LED wall packs, you would be wrong to think so. The LED wall pack by contrast helps you recover the initial investment in the long run.
Bad Color of Light, Worst CRI
The high-pressure sodium lights when compared with LED wall packs of today, emitted yellowish hue than a bright white hue you get to see when you make use of LED wall packs. Also, the HPS lights had the worst ever color rendering ability -- that which is never the feature of LED wall pack light. The LED wall pack having a CRI of 70+ is considered cool by the lighting experts when it is to be used for outdoor lighting.
Now, let’s get to discuss the different types of LED wall packs.
LED Wall Pack -- Major Types
If you are user of LED wall pack for the very first time, choosing the right kind of wall pack can get really difficult as the product pages on their websites may not tell you enough about these light fixtures. So, here’s a brief note on the common types that exist in the market.
LED Mini Wall Pack and LED Security Wall Pack
Both of these Wall packs provide lighting in the same way as any conventional wall packs do. And so these are better known as forward-throw wall packs, when the light emitted is more wider in distribution than in length of the wall. The conventional wall packs get defeated when compared with these wall packs as they throw some light in the backward direction apart from forwarding direction and a lot of light gets wasted thus. If a wall pack emits light in the beam angle of 30-40 degrees, it may well be used for accent or ambient lighting, but when the beam angle is 110 degrees or more, the wall pack makes itself useful as security lights.
LED Semi Cut-Off Wall Pack and LED Full Cut-Off Wall Pack
A full cut-off LED wall pack would mean light is not being emitted above a certain horizontal line and all the light then gets emitted in the downward direction and also slightly forward. On the other hand, a semi cut-off would have half of the light being emitted in the line below a certain horizontal line and half of the light emitted beyond that same line. So, you semi cut-off wall pack helps you achieve both uplighting and downlighting. Such wall packs help to provide architectural wall-washing effects and great for decorative purposes.
Rotatable LED Wall Pack
This kind of wall pack is special in the sense that it can be rotated when in operation and so used for providing light in upward, downward or in both directions. This kind of wall pack is used to illuminate not just architectural building, but also industrial and commercial buildings as it can provide for the best kind of safety and security.
The Bottom Line
The LED wall pack is available in 4000K and 5700K serves so many purposes as highlighted in this blogpost. That said, it also helps to cut down on your utility expenses by up to 80%. What more you need? If you are looking for automatic turning On or Off of the lights, you may have an LED wall pack with in-built photocell. Check this out and all other varieties on LEDMyPlace.
