Features

• Efficient power supply – other LED tubes are unregulated and run the risk of premature failure with fluctuating various input voltage. These LED Tubes have been specifically modified to both withstand transients (spikes) and varied supply input.

• High compatibility – Testing has been done with various magnetic ballasts which have shown high compatibility, resulting in an easy fit with only the starter and capacitor needed to be removed.

• Aluminum housing – Effectively removes the heat from the LED array, extending life-span and reliability.

Note: Efficacy refers to Luminous Efficacy which is related the overall efficiency.

Effective Lumens Measurement

LED Technology differs from all previous light engine designs in that the light output of any LED lamp is wholly directional. Previous light technologies consist of Omni-directional light sources emitting light in all directions. Various housings around the actual lamp have attempted to focus reflect light into wanted directions. However even the most efficient of reflector designs still result in significant losses.

A fluorescent tube, by mere design, emits light in all directions. The luminous flux rating manufacturers put to their lamps is representative of this.

Below is an example of the mean lumens rating of standard Halo-phosphate T8 Fluorescent Tubes

Description	Power (Watts)	Lumens	Mean lumens
2 ft.(600mm) T8 Fluorescent 4000K	18	700	(700*80%)=560
4 ft.(1200mm) T8 Fluorescent 4000K	36	1400	1411*80%=1128

 

Standard T8 Halo-phosphate has a luminous efficiency of approximately 70 lumens per watt.

It should be noted that many manufacturers only quote the initial lumens on their Fluorescent lamps. Initial lumens represent the light output of the lamp in the first 1000 hours or less of operation. Mean lumens is more representative of the light output after this initial “burn in” period and can be 20% less than the initial lumen rating. Mean lumen of T8 LED tube light is only about 3% less than the initial lumen rating.

By comparison the LED T8 tubes emit light in one direction only at a beam angle of 120º which is 1/3 the light radiation pattern of standard fluorescent tubes.

The vast majority of fluorescent tube fixtures are designed to emit light in one direction, with a similar 120º beam spread, a large proportion of the total light output from a tube is lost, even with chrome reflectors which have been shown to improve light output by only 30%
Therefore when comparing LED T8 Tubes against a fluorescent T8 a more representative measure is needed to indicate a comparative light output.

With various tests that have been performed, the actual light utilization of a standard T8 fluorescent tube has been determined to be 65% on average. Our LED Tubes have a utilization efficiency of 95% due to their directional nature. T8 LED Tube Lights utilize ~45% more of their total light output when compared against a standard T8 fluorescent.

T8 LED Tube Retrofit Installation Guide

• Our LED Tube Lights are designed to be an easy retrofit in replacing standard fluorescent tube lights.

 

• Only a simple removal or bypass of the electronic ballast and capacitor is needed.

• T8 LED Tube Lights operate at 110VAC applied to the pins on either end of the tube.

 

Power should be applied to both ends of the tube; on either pin (the pins are internally shorted/connected).

Rewiring Diagram for Traditional Magnetic Ballast
The tubes are compatible with standard magnetic ballasts designed for 8 to 40 watt fluorescent.
If in doubt, remove / bypass the ballast and starter and wire the tube as per the rewiring diagram for electronic ballasts.

Rewiring Diagram for Electronic / High Frequency Ballast

The tubes are not compatible with electronic or high frequency ballasts. In such fixtures electronic ballasts must be removed or bypassed. Starters must also be removed. Any correcting capacitor should also be removed from the circuit. This is a relatively simple operation and just involves connecting the input phases to the end cap wires as pictured below.

A simple terminal connecting block can be used to join the mains input wires to the end cap wires.
