Fluorescent vs LED Tube

As an LED lighting professional, I realize that LEDs are a new concept, not yet known or fully understood for many people, who don´t understand the difference between Fluorescent vs LED Tube.

Briefly, LEDs or light–emitting diodes are semiconductor devices that produce visible light when an electrical current passed through them, and there are many LED options.

Some look like lights or light bulbs you know, others don’t look like anything you have seen before, both in shape, color, intensity, and flexibility.

However, their main advantages are that LEDs consume much less electricity and last on average eight times longer than the standard bulb.

Indeed the cost of LEDs is also greater, but the cost is returned quickly through long-term savings.

The truth is there is great opportunity and variety with LED illumination, and great savings too.

Getting to Know LEDs

For the person just getting to know LEDs, general lighting is the place to start.

General lighting is nothing fancy, it is simply the lighting you see everyday in your home, office, etc.  The most commonly sold and installed light is the LED tube, and it also is one that pays for itself the fastest.

Fluorescent tubes come in three common wattages and most of the time more than one tube fit in a single fixture.

The LED equivalent to most fluorescent lamps will be 22 or 18 watts.  However LEDs do not use watts to describe the light’s brightness.

LEDs are measured in Kelvin, a lighting term used to describe color appearance.

Lumens measure the light’s saturation per second, or its brightness. Lumens best articulate the comparison of fluorescent tubes to LEDs.

In addition, home renovation retailers mostly sell a lower quality version of LED lighting.

If businesses want a smart investment, they will invest in a commercial grade product.

While one LED tube can replace 2 fluorescent tubes in many cases.

Replacing one T8 32W tube with one LED 16W Tube will save right at $20 a year, provided you use the lighting 7 days a week, 12 hours a day.

The cost of one LED 16W tube can be somewhere in between $5 and $7.

So the investment pays for itself within 3 to 5 months.

The next thing that should be discussed about LEDs is their installation and how it differs from the standard florescent tube:

Fluorescent tubes require ballasts, while LED tubes do not.

Ballasts are inductive devices that use energy in addition to the energy needed for the fluorescent lamp itself.

Ballasts are needed in fluorescent fixtures because the negative resistance characteristics of the tube design, which would otherwise rise to destructive levels.

LED tubes do not require ballasts in order to work, and they can be installed either on standard fixtures by removing the ballast, or using ballast compatible tubes.

The advantage of the ballast compatible tube is that they are “plug and play” and function with or without a ballast.

However,  ballasts have a life expectancy of about 5 years, so eventually the ballasts have to be removed or replaced.

Thus, the advantage of the plug and play tube is that it buys you sometime before you eventually remove the ballasts.

Some businesses choose to remove the ballasts at the time of LED installation.

The plug and play tube only averages $1 more than the non-ballast compatible tube, so the cost difference is minimal.

While rewiring the ballast out of the fixture system will cost on average $25, which cost less than replacing the bad ballast anyway.

Once again, a lighting specialist can help you through the pros and cons of each option.

In summary, when it comes to LED lighting, every single light you see has an LED equivalent.

Over the course of the next few months and years, homes and businesses will be changing to this technology, and eventually LED lighting will be everywhere.

I would love to think this change is environmental friendly motivated, but reality is it is about simple economics.

LED lights pay for themselves and save money, and in the long run any savvy person knows that money is the bottom line!
