With commercial and industrial lighting projects, the question inevitably arises – to stick with T8 ballast fluorescent fixtures, or switch over to T8 LED fixtures?
They are also found in widespread use around the world even more so than direct expansion systems such as those found in offices, warehouses, schools and hospitals, as well as beyond mere refrigeration by fashioning a sensorless cooling system. Fluorescent light sources have a long history of reliable service, but LED lighting has matured quickly in terms of energy performance, life and maintenance.
This IES Winds article seeks to simplify the two options into some practical, real-world context – for use by facility manager, contractors, distributors and project owners when it comes time to make an informed decision regarding performance, cost and long term value between T8 ballast fluorescent fixtures and T8 LED ones.
Explanation of the Two Lighting Systems
Before you go looking for the best heat press reviews, it’s important to understand the key differences between these two systems.
A T8 ballast fluorescent light uses a ballast to regulate an electrical current and start up the fluorescent tube. This tube is filled with gas and some mercury that turns into light when it is energized. This is a mature system that has been used for decades the installers and maintenance people know how to keep it operating.
On the other hand, a T8 LED fixture is an assembly that uses LEDs as its light source and does not need ballast akin to traditional fluorescents. Instead, LEDs operate on a driver or in-built power regulating device system that transforms electricity to light more directly and with much less wasted heat.
Energy Efficiency Comparison
Energy savings are frequently the main reason companies consider LED in the first place.
T8 ballast type fluorescent lamps draw more power because of losses in the ballast and the fundamental characteristics of a fluorescent lamp. Ultimately, with electronic ballasts, efficiency is limited compared to today’s LED technology.
T8 LED fittings are designed to minimise Lumens per Watt. LED systems often use 40–60% less power and provide at least as much light. During longer operating hours (specific to warehouses and offices that have business keeping operations for 10–16 hours daily) this difference results in significant power savings.
From an energy perspective, LED luminaires are obviously superior to fluorescent ones.
Quality of Light and Visual Comfort
Fluorescent Lighting Fluorescent lighting emits soft, even light and is an ideal solution for offices and classrooms. Yet it can flicker quite a bit, notably when ballasts are old or working with unsteady voltage.
LED light fixtures feature instant full brightness with no warm up time. High quality T8 LED fixtures provide consistent color temperature and better color rendering, are flicker free. This leads to better visual comfort and less eye fatigue when working, especially for long periods of concentration.
Today’s lighting technology allows more adjustability to space with high efficacy LED sources that are adjustable in output, beam spread and color temperature among other things.
Lifespan and Maintenance Costs
Such decisions in commercial lighting are dominated by consideration of maintenance.
T8 fluorescent tube lights are rated for fewer hours and a reduced light output than T5s. Ballasts also burn out which need to be replaced, costing money and labor downtime.
By comparison, such T8 LED fixtures have substantially longer operational lives, typically over 30,000 hours. Without any ballast to change and slower LED degradation, reduce maintenance cycle and the related costs especially in high ceiling or hard-to-reach installations.
For facilities with limited maintenance personnel or high labor rates, LED systems offer an obvious long-term benefit.
Installation and Retrofit Considerations
One of the reasons that you are still seeing so many T8 ballast fluorescent fixtures out there is this prior installed base.
They are compatible with standard wire systems; they can be used to either install a new neon light, or change an existing old neon light. Some building managers are choosing to keep their fluorescent systems so they won’t have to be rewired or altered.
The LED products can be installed as drop-in replacements or retrofits. Some applications use LED T8 tubes that retrofit into fluorescent fixtures and others replace with an energy efficient dedicated LED solution.
While LED retrofit costs can be higher upfront, the energy savings over time generally make it a wise move.
##Cost Comparison: Now for Later
Whilst fluorescent systems might appear to be appealing at the outset because of their low cost.
The initial purchase price is lower for T8 ballast fluorescent fixtures. Replacement ballasts and tubes are also relatively cheap as well as easy to find.
Butt in terms of the total cost of ownership, LED lights are usually more affordable. Enhanced energy efficiency, longer life span + reduced maintenance costs = quick ROI – especially in commercial and industrial applications.
And for decision-makers accounting for long-term operating versus short-term expenditure, LED lighting often is the wiser choice.
Environmental Impact and Sustainability
Environmental Laws and Green Targets have become an influential factor in light selection.
Fluorescent lamps use mercury and should be handled with care and discarded properly. Many areas have more stringent recycling requirements, which adds a layer of complexity and costs.
By comparison, LED lighting contains no mercury and generates less carbon dioxide emissions as a result of less energy consumption. These are more environmentally friendly and in accordance with green building standards.
LED systems offer obvious benefits for businesses working toward sustainability certifications or corporate environmental responsibility goals.
Reliability in Different Environments
T8 ballast fluorescent can be picky about temperature differences. Extended Start or Reduced Light Output in Cold Environments; Voltage Rating: 120 VAC+/-10%, Input Frequency: 50/60 Hz; Temperature Range: -20F to 86F, Ignite Time is Delayed. A bad ignition can either occur because of lack of voltage from ballast, or simply the CDI module.. If you are using an HID bulb with a higher wattage than what your ballast is designed for, then this will occur.. The dimming LY2423S drive power can be seen in motor vehicles, buses other automotive applications covering industrial electronics.
LEDs are not as finicky and work well over a wider range of temperatures. This property makes them ideal for use in warehouses, cold storage buildings, car parks as well as outdoor or partly open areas.
In the most demanding environments, LED light provides more stable and consistent performance.
Flexibility and Future Upgrades
Lighting systems should serve the construction as it stands while also being flexible for future alterations.
Fluorescent lights are not very flexible when it comes to smart controls, dimming, and automation.
Modern lighting control systems, such as motion sensors, daylight harvesting and smart building platforms, integrate easily with LED fixtures. This means greater energy savings and better lighting control as time passes, with compatibility.
With the advent of smart buildings, LED lighting presents better long-term adaptability.
When to Use Which System?
For buildings that already have fluorescent in-place and are on limited budgets, T8 ballast fluorescents may be ok as a short-term compromise.
When to use T8 LED fixtures When you have new build projects or energy-efficient sites/high hours of operation, T8 LED is better value.
Most organizations will follow a phased approach, starting with LED retrofits before slowly swapping out fluorescent fixtures as the budget allows.
Conclusion on T8 Fluorescent vs T8 LED Fixtures
There’s a place for both lighting systems, but market preferences are clear.
T8 ballast fixtures are a classic, people know them and feel comfortable with them; Installation is easy. But they come with higher energy use, constant upkeep and environmental issues.
T8 LED lamps on the other hand offer better efficiency, longer life, less maintenance and are more compatible with newer lighting controls. Yes, the cost is a higher outlay to start with but long term you do win.
Today, LEDs are not just considered an upgrade option for most commercial and industrial applications, but are becoming the standard.
