LED vs Fluorescent Tubes

Light Bulb Efficiency Comparison

Fluorescent pipes have been in existence what seem like "forever" - they offer inexpensive illumination for almost all commercial places: hallways, workplaces, warehouses, etc. But just because one thing has been around "forever", does which make it ideal answer?

We explore the real difference within our LED vs. Fluorescent pipes match-up, an initial of several comparison posts to come - weighing the commonly frequently made use of lighting services and products to their Light-emitting Diode options. There are three primary places worth comparing:

1. Energy Consumption

Once the deciding factor for several home managers and companies, power usage or electricity use could possibly be the huge difference manufacturer for not only light however, many other operational technologies of a building. Even though many facilities supervisors check out put in energy saving HVAC systems, not many are familiar with the potential savings with LED pipes compared to their particular current fluorescent lamps. This is especially true for property places with 24/7 lighting effects (meaning the light is on all day long and night) like parking garages, hallways, lobbies, amenity spaces and lots of other areas.

So how much difference does a Light-emitting Diode tube make in comparison to a fluorescent? Here is a simple comparison chart involving the two:


Ballast Factor

Operational Wattage

Yearly intake (24/7 operation - 1 light bulb)

34 Watt T12 Fluorescent Tubes


43 Watts

376.68 kWh

16 Watt T8 Equivalent LED Tube

16 Watts

140.16 kWh

Whilst the huge difference is 236.52 kWh, remember this will be for one light bulb just! In the event that cost of energy sources are $0.11 per 1 kWh...with only one light bulb the building would save around $26.00.

Now most of us know we do not have an individual fluorescent bulb around, usually a building is setup with accessories which have two light bulbs. Let us assume a 100 (reasonable estimation for bigger commercial properties) fixtures with 2 pipes per installation:

Fluorescent Procedure

Annual Energy intake: 75, 336 kWh
Yearly Operating Costs: $8, 286.96

LED Procedure

Annual Energy intake: 28, 032 kWh
Annual Working Expenses: 3, 083.52


Annual Energy Savings: 47, 304 kWh
Annual Working Savings: $5, 203.44

This is certainly a big number to reduce away from energy bills, and enhance the performance of a house. By changing the kind pipe in the fixture. Take into account that the greater number of pipes becoming changed into the residential property, the larger the annual savings. Depending on the kind of current fluorescent pipes (T4, T8, T12), there clearly was a possible both for ENERGY and WORKING cost benefits with Light-emitting Diode tubes.

Yes, we understand the next concern coming up: but if 16 Watt LED T8 tubes replace 34 Watt T12 fluorescents, will that not reduce steadily the lighting degrees of the region?

2. Lighting Efficiency

The response to the above question plain and simple: NO, not only will the light levels improve, but will preserve their particular brightness levels for your duration of LED tube's life. Which is not stated the same for fluorescent tubes.

How many times perhaps you have moved in an underground storage or down a hallway, and then spot the ominous light flickering. As fluorescent tubes expire, their particular light levels reduce somewhat...and sooner or later they begin to flicker. Compared, LED pipes usually do not flicker or reduce the number of light coming from the bulb. The light level always continue to be equivalent - whilst the pipe reaches the termination of its life, it merely stops working. No decrease in illumination, no flickering, & most importantly no creepy knowledge for your tenants!

The following may be the average lumens (amount of light from the pipe) both for kinds of light bulbs:
  • 32W T12 Fluorescent: 1, 800
  • 16W Light-emitting Diode Tube: 1, 900

Remember, the LED the lumens continue to be exactly the same no matter how lengthy its already been working as the lumens depreciate for the fluorescent as time passes (as mentioned above)! While this distinction may not seem like a great deal, but once discover a specific location involved - such an underground parking garage - light levels make a staggering huge difference:

3. Light Efficiency

From the comparisons above, it's fairly clear that LED tubes contain the benefit as an overall lighting solution. Luminous effectiveness is actually how good a light light bulb produces visible light when compared to the ability eaten together with number of lumens generated. Merely, it really is what amount of lumens are manufactured per watt.

If we stick with the two types of tubes we have been contrasting so far, we obtain the following outcomes

  • 32W T12 Fluorescent: 53 (1800 lumens/34 watts)
  • 16W Light-emitting Diode Tube: 119 (1900 lumens/16 watts)
This is certainly above DOUBLE the effectiveness of standard fluorescent pipes. Require we say other things?
