How The Isle Casino Of Pompano Park Converted To LED Lighting
The Isle casino located in Pompano Beach, FL is a premiere property with hundreds of parking lot lights. Our designers replaced 400W metal halides with 150W custom painted Slim LED Shoe box Lights, yielding a 62.5% reduction in lighting energy consumption. The Isle Casino is now able to enjoy improved lighting while deterring unwanted intruders and making customers feel safe and secure.
High Intensity Discharge Cobra Head Lighting
HID Lighting replaces the ﬁlament of a light bulb with a capsule of gas. The light emanates from an arc discharge between two closely spaced electrodes. This discharge is hermetically sealed inside a small quartz glass tubular capsule. HID Lights require a ballast, which carefully regulates gas supplied to the capsule. The beneﬁts to this versus a standard halogen bulb is that this light more closely approximates the color temperature of natural daylight.
High Intensity Discharge is an overarching term for a gas-discharge light. They are the oldest type of electrical light. Among the common types of HID lights are mercury vapor, low and high pressure sodium and metal halide lamps. Other less common variants include ceramic metal halide and xenon short-arc lamps. HID lamps produce light by sending an electrical charge or “arc” between two tungsten electrical conductors (electrodes) and through an ionized gas (also known as “plasma”) which is housed inside the bulb. HID lights require ignition which is typically provided by a voltage pulse or a third electrode (an additional metal part) internal to the bulb. Once lit the electrical arc begins to evaporate the metal salts inside the bulb which signiﬁcantly increases the luminous power of the bulb while simultaneously improving lighting eﬃciency. HID lighting requires a “warm-up” period because the lighting intensity is dependent on and changes as the material inside the bulb is evaporated into plasma. Additionally, as the light heats up it requires additional voltage to operate. Voltage requirements in HID bulbs are balanced by an electrical ballast (essentially a device that limits electrical current to that required to operate the lamp). As the HID light ages, more and more voltage is required to produce the same amount of light until eventually the voltage exceeds the ﬁxed resistance provided by the ballast and the light goes out (fails). HID lights become less and less eﬃcient over time because they must use more and more voltage to produce the same lumen output as the light degrades.
HID Fixture Maintenance
Proper maintenance of any lighting system is essential to maintain levels of illumination
necessary for productivity, merchandising, visual comfort, safety, and security. If one
individual component fails and is allowed to remain in the lighting system, costly damage to
other components can result. Major repairs can often be avoided by simple maintenance
procedures and timely attention to small problems, such as replacing burned-out lamps, But
more often times than not, repairs accumulate as the cost to repair / replace one bulb can
add up to several hundred dollars.
Lamps should be replaced as a group at scheduled periodic intervals, based on rated life,
minimum acceptable lighting levels, and system operation cost. Your lamp supplier has
additional information available regarding lamp maintenance procedures.
In addition, to obtain normal ballast life and maximum efficiency from an HID lighting
installation, fixtures should periodically be inspected for:
• Lamps cycling on and off
• Heavy lamp discoloration
• Dim lamps
• Slow-starting lamps
• Inoperative lamps
• Dust and dirt
In addition to this, Lamps should be checked to be sure the proper lamp type is being used,
according to the information on the label of the installed ballast. Many lamp types currently
offered, such as metal halide and high pressure sodium lamps, are physically
interchangeable, but not electrically interchangeable.
High Grade LED Lighting
LEDs don’t have a filament to burn out or break.
Therefore, they last much longer than
conventional bulbs. Given that a very small
semiconductor chip runs an LED, they are very
durable and tend to last many thousands of
hours. Moreover, LEDs are “instant on,” much like
halogen lamps, and thus convenient for use in
applications that are subject to frequent or
potential on-off cycling. Conversely, HID lamps
are more fragile and have to warm up (15 – 25
Seconds) during ignition.
LED Lighting Benefits
LEDs have an extremely long lifespan relative to every other lighting technology (including
HID). New LEDs can last 100,000 hours or more. The typical lifespan for an HID bulb, by
comparison, is 10-25% as long at best (10,000 – 25,000 hours). LEDs are also extremely
energy efficient relative to every other commercially available lighting technology. In addition
LEDs require far fewer accessory lamp parts such as ballasts and capacitors which are
designed to fail and be replaced. As a result maintenance costs and hassle associated with
LED lighting is virtually non existent .
1) Directional: Light is emitted directionally (over 180 degrees versus 360 degrees which
means there are far fewer losses from the need to redirect or reflect light).
2) Warm-Up: LEDs have faster switching (no warm-up or cool-down period).
3) Color: LEDs can be designed to generate the entire spectrum of visible light colors
without having to use the traditional color filters required by traditional lighting solutions.
4) Accessories: Size: LEDs can be much smaller than other lights meaning better durability
in storms outside or putting lights in locations not possible before.
5) Energy Efficiency: LEDs are extremely energy efficient relative to every other
commercially available lighting technology.
Why would LEDs put HID lights out of business?
Source vs system efficiency is the main reason. So what is source efficiency versus system
efficiency? HID lights are very efficient when measured at the source (lumens/watt). This
measurement, however, does not take into account the amount of light that actually hits the
target area (system efficiency). System efficiency is affected by a myriad of factors that
include losses due to trapped light, protective covers or lenses, non-standard operating
temperatures, and losses due to power conversion. System efficiency for HID lights is
generally only 25% of the source efficiency, as compared to LED lights (whose system
efficiency is closer to 50% of the source efficiency). The result is a much more effective light
in the case of LEDs.
Additionally, HIDs bring with them a myriad of potential problems. The major items include
repetitive maintenance and replacement costs both in parts and labor (HIDs have a much
shorter lifespan than LEDs), potentially hazardous waste (internal mercury) and dangerous
emissions (UV) in the event that the bulb is broken or the casing experiences some type of
failure, and small things like required warm-up times, inability to effectively dim, and typically
shorter warranty coverage.
The major advantage of HIDs is that in some cases (particularly with low and high pressure
sodium bulbs) the initial purchase price will be much lower. Typically LEDs make up for their
higher purchase price with reduced maintenance and energy costs across a specific payback
period. Curious about payback period and return on investment analysis? Give us a ring and

Additionally, another specific tradeoff with LPS and HPS bulbs in particular is that they are
monochromatic yellow with an abysmal Color Rendering Index (in other words, everything
illuminated by them shows up yellow. You literally can’t see color when using LPS or HPS
LEDs are a simple invention with huge potential to change the lighting industry for the better.
While the technology has been gradually adopted, it is advancing rapidly and already beats
the competition in many if not most applications.
Isle Casino Project Data
225 Fixtures were replaced with energy efficient
LED Lighting, this provided a substantial savings
as represented in the chart below.
Additional savings were achieved by outfitting
each individual unit with a Photocell Light sensor,
this ensures the new Lighting is only turned on
when it is dark outside.
Maintenance of parking lot light fixtures has been
virtually eliminated resulting in less down time and
more efficient operations throughout the Casino.
Return On Investment
Due to the superior energy efficiency of LED Lighting, the Isle Casino will see 100% Return Of
Investment of their project completed in just two and a half years! After that, the savings
become extra free additional capital that can be invested into other areas of the casino.
