What’s in it for you…
Fluorescent lamps are energy efficient, cost effective alternative lighting sources with many benefits to you, the user, and the environment. They use less electricity than a standard incandescent bulb, last longer, and give off less heat, making them a cost-effective lighting alternative.
Better Energy Efficiency
T5, T5HO and T8 Tri-phosphor lamps provide more “light” using less energy. Tri-phosphor fluorescent lamps reduce energy consumption by up to 40% when used with electronic ballasts. Plus, these lamps offer improved color rendering, and the linear distribution of light is uniform for more effective lumination of the task area.
Using electronic ballasts instead of magnetic ballasts provides more light output with less wattage—20,000 cycles per second vs. 60 cycles with the magnetic version—and runs quieter and cooler. Dimmable electronic ballasts offer the best of two worlds, energy saving electronics and the ability to adjust the amount of lighting of the task area.
Energy waste is eliminated with occupancy sensors. When the light senses an occupant, it turns on. If no activity is detected within 15 minutes, it turns off. Occupancy sensors contribute an energy savings of up to 70%.
High fixture efficiency and optical controls deliver the peak candlepower needed to produce desired illumination levels from high mounting heights.
Additionally, it is important to consider the following key features:
- Instant on/off control
- Improved horizontal and vertical illumination
- 85 CRI (fluorescent) v. 65 CRI (metal halide)
- 95%+ Lumen Maintenance (fluorescent) v. 50% Lumen Maintenance
- (metal halide)
- Longer life – up to 25,000 hours
- 80+ maintained Lumens per watt
- Energy savings of 25% or more vs. HID fixtures
Reduced Eye Strain
Fluorescent task lighting offers relief to eye strain—that silent, often overlooked inhibitor of productivity. Eye strain occurs when the muscle of the eye must continually adjust the iris to the brightness and contrast of the task. If the light is too bright or too dim, if the contrast of the task is too high, or if there is too much glare, the eye becomes overworked as it struggles to compensate for the environment.
The result? Distractions that reduce productivity: burning eyes, headaches, drowsiness, even neck and back pain.
If 80% of all sensory experience is visual, why not make it pleasant? Augment lower ambient light levels with task lighting. Task lighting evenly directs the appropriate amount of light to the task with minimum glare, reducing the need for the eye to make frequent adjustments and enhancing the workers environment.
More reasons to consider fluorescent lighting:
- Fluorescent light stays brighter longer. Over their 24,000-hour lifetime, fluorescent lamps maintain 94% of their luminosity as compared to 65% for HID. And fluorescent lights are less costly to operate, averaging 55% savings per fixture over HID.
- Improved lamp life. Fluorescent lamps last two to three times longer than metal halide lamps of 400W or less, based on lamp manufacturers’ published data.
- Excellent lumen maintenance. T5 and T8 fluorescent lamps lose only 5–6% of their lumen output between the rated initial and maintained lumens (maintained lumens are calculated at 40% of rated life). By contrast, standard metal halide lamp lumens typically deteriorate about 35% over the same period. As the lamps continue to age, the difference becomes even more pronounced.
- Energy efficiency. The higher lumens per watt of fluorescent systems translates into big energy savings. Maintained footcandles are almost always better per energy dollars spent.
- Fluorescent light has a high color-rendering index—up to 85 compared to 65–70 for HID. This can be especially important in warehousing, where accurate reading of color codes and color-coded tags is essential for error-free operation.
- Instant on. Fluorescent light comes on at full light output instantly, unlike HID, which can take 15 minutes to reach full brightness.
- Dimmable and occupancy sensor capabilities. Fluorescent lights further reduce your energy costs by allowing lights to turn off in low-activity areas.
- Energy company rebates. APS and SRP offer rebates to companies who significantly reduce their energy demand.
