Solid State vs. LED Bulbs for Outdoor Lighting – Which is Best
LED vs Solid State Lighting

Since the introduction of LEDs (Light Emitting Diodes) into the low voltage lighting scene, manufacturers have created two distinctly different lines of products for the outdoor lighting industry. They are solid state lighting and LED replacement lamps. Let’s take a brief look at solid state vs LED bulbs for outdoor lighting.

Solid State LED Lighting:

SSL, or Solid-State Lighting, is a term used to describe an LED luminaire that is a complete lighting component built for a specific application.  These systems are generally more compact than the traditional “lamp” driven lighting system due to the more compact nature of the LEDs themselves.

These systems are comprised of an LED chipset and lens that is thermally bonded to a fixture body. They are designed to pull heat away from the LED board through a series of external fins. These fins are used to increase the surface area of the fixture to the outside air for cooling purposes.  SSL types of light fixtures generally have a permanently sealed fixture body to keep moisture and air out of the inner components promoting longevity.

LED Bulbs:

For more than 50 years, low voltage lighting systems have employed the use of miniature incandescent and halogen lamps to illuminate gardens across the world.  When the LED came along, around 2005, a solution was needed to upgrade the millions and millions of existing lighting systems out there, without incurring the expense and utter waste of having to completely tear out all those systems. Enter the LED bulb.

LED bulbs are constructed in such a way, that they mimic the same shape and size as their halogen and incandescent lamp counterparts. They fit in all the same light fixtures that have been used for years, but at a fraction of the energy consumption.  This allows us to use the same tried and true brass, copper and stainless-steel lighting fixtures we have grown to love. But now we have a much more energy efficient option.

Pros and the Cons of Each

As with anything else, there are always positives and negatives on both sides.  So, let’s break down a few of each:

SSL (Solid State Lighting)

PROS

  • Better at dispersing heat away from the heat sensitive, electronic components
  • Greater longevity and service life (5-7 years)
  • Can often be slightly more compact in size

CONS

  • Higher cost to purchase over lamp style fixtures
  • Fixed lenses and beam spreads which cannot be changed (in most cases)
  • Fixed lumen output (brightness) which cannot be changed (in most cases)
  • LED failure results in having to replace the entire fixture and LED together (more waste in the landfills)
  • Hard to adapt to changing landscapes over time with a fixed lumen and beam spread

LED Bulbs

PROS

  • Low cost and easily accessible (only slightly more than a quality halogen lamp)
  • Fits into existing fixtures, so upgrading is nearly as easy as simply changing out a light bulb
  • Just as energy efficient as an SSL option
  • Lamps can easily be swapped out to brighter versions with differing beam spreads or color to accommodate landscape changes over time where an SSL cannot.
  • Bulbs allow the ability to “tweak” a lighting design without replacing and re-wiring in completely new light fixtures

CONS

  • Shorter lifespan than SSL systems due to the inability to disperse heat effectively (2-3 years)
  • These LEDs are placed in fixtures that are slightly more susceptible to the elements, which can reduce service life also.

Lighthouse Outdoor Lighting® has found that LED bulbs are the most adaptable and cost-effective option for our clients today.  LED bulbs give us the ability to upgrade thousands of our client’s existing halogen systems to LED, without the high cost and waste of replacing the entire brass fixture.

LED bulbs also allow maximum flexibility to design our initial lighting plan. We can still make subtle tweaks and changes very easily after the installation has been completed.  The LED bulb is quickly becoming one of the least expensive components in our lighting systems.  Efficiency in the manufacturing processes and better standards of quality control are beginning to make LED lamps nearly as affordable to replace as a quality halogen lamp.

Prior to LEDs, Lighthouse used to change out all halogen lamps on an annual basis to keep the lighting looking fresh and even for our clients.  With lower and continually falling costs of LED bulbs, we now recommend a complete LED bulb re-lamp every three years to keep the light fresh. This is a good way to keep up with the current technology and quality of LED bulbs that are continually hitting the marketplace.
