T-8 Flourescent LED Tube

started May 04, 2016 by request from administrative staff
**********************************************************************

Congo, Your initial request was for simple information about financial topics

******************************************************************************************************************************************

In General, LED T8 tubes run at 1/3 the power of T8 flourescent tubes (23 W vs. 60 W).
In General, LED T8 tubes last 3 times longer than T8 flouresent tubes. (15 yrs vs. 5 yrs )
In General, LED T8 tubes with NO ballast cost the same to install
as replacing a T8 flourescent ballast and two tubes. ( about $50 )

The TOTAL cost of retrofiting with LED tubes should include future MAINTENANCE.
* There are four different flourescent wiring methods in Congo. I rewire each to a standard each time.
* In General, LED T8 tubes require no future maintenace ... if the ballast is removed.
* Always, If the ballast is not removed, and the new LED tubes are the kind that require the old ballast,
... then when the old ballast eventually fails, Congo will pay $100 each to a contractor for replacing each ballast.
... That is twice the cost of my current method.

or
Congo will pay $100 each to remove the ballast, eventually, and install LED tubes with NO ballast.
...
I have chosen to install LED tubes with NO ballast, thus eliminating the future maintenance.

This is comparison for CFL flourescent bulbs vs. LED bulbs.
A little out of date, but it applies to lighting in general.

Church Sanctuary PAR56 LED Retrofit an example.

ENERGY SAVINGS = 93%

LONGER LASTING PRODUCTS = REDUCED MAINTENANCE COSTS
LESS FREQUENT RELAMPING = INCREASED WORKER SAFETY
INCREASED LIGHT QUALITY
INCREASED LIGHT LEVELS

For Congo, calculations should be similar. Prices on these large bulbs coming down.

Reasons to install LED Linear Tubes in hallways.

1. LED Replacement tubes are 30% More Efficient than flourescent.

So not only do you get more light from a LED replacement bulb, they use less wattage.
LED replacement bulbs only use 22 watts vs 28-32 watts with T8 making the LED 30% more efficient.

2. LED Is A Directional Light Source

The LED replacement bulbs emits light at a 110 degree pattern vs the 360 degree pattern given off by T8 fluorescent bulbs.

3. LED Transfer Light vs. Heat

A LED fixture uses its energy to produce light.
Most lighting sources including fluorescent use heat to generate light which is why traditional incandescent, metal halide and fluorescent are losing favor with property owners.

4. LED Still Give Off Light At End-Of-Life

A fluorescent bulb at the end of its life is very simple to spot, because it is DEAD, nothing left. A T8 bulb is considered end-of-life at 60% of its light output, which equates to roughly 14,400 hours.

LED replacement bulbs on the other hand, calculate the end of life at 70% which is approximately 50,000 hours.

In order to keep up with LED, you will have to replace the T8 bulbs 3.5 times

5. LED Replacement Bulbs Have No Mercury

One of the most important differences lies in the fact that there is no Mercury or Glass Content with LED lighting.

In the State of Washington alone, over 10 Million lamps are disposed of in landfills each year.
Those 10 Million lamps hold roughly 400 lbs of toxic Mercury waste that gets deposited each year.
Washington State estimates that only 2 out of 10 bulbs are effectively recycled.

6. LED Does Not Give Off UV

LED replacement bulbs does not emit any light in the non-visible light spectrum (UV).
UV/IR light causes colors to fade in fabrics, signage, while also being the leading cause for eye strain and eye fatigue.

Fluorescent T8 bulbs emit UV/IR light.

7. LED Makes Air Conditioning More Efficient

LED fixtures contribute little to none in regards to heat gain in a room or air conditioned space.
The LED generate less heat. Less heat means that the Air Conditioning system does not have to work as hard.

This is vitally important if you are doing a new build or upgrade as you may be able to utilize smaller A/C systems to heat the same area.

8. LED Provides 70% More Light

The beam angle of the LED replacement bulb is 110 degrees. This means that all of the light generated by the LED bulb is focused in the 110 degree area.

The T8 bulb on the other has a beam angle of 360 degrees.
That means the majority of the light generated by the T8 bulb is going out the sides and top of bulb, which does not benefit the intended target.
