Why are we upgrading our LED package?

Christen Hartman

Answer

As with any new technology, the LED industry is no exception and has made major advancements. We are happy to provide you with the most up-to-date product in today’s LED offering.

  • Improvements in LM80 indicates longer consistent light output over the life of the LED. Light emitting diodes degrade slowly, usually not noticeable to the human eye, diminishing light output over time.
  • Lower power use (watts) points to a reduction in overall operating costs. Electricity costs are not going down in price anytime soon, but our new and improved LED will help you save more on your electric bill.
  • Lower power use (watts) in conjunction with higher efficacy means more light with less heat. Reduced operating temperatures extend the life of an LED.
  • Circuit board improvements increase life by allowing the LED chip to operate at a cooler temperature.

We look forward to further improvements and we are committed to providing you with the best LED solutions for outdoor lighting.

How do I obtain a previous version as a replacement?

Christen Hartman

Answer
We have reserved limited stock of our previous version to fulfill warranty and service related issues. If you return an Integral Lighting fixture for warranty, we will replace it with the same LED package to ensure your light output remains equivalent.

Keep in mind that all LED packages degrade slowly in the amount of light output, therefore, we do not guarantee a perfect match on output brightness.

How is the new circuit board improved?

Christen Hartman

Answer

Our earlier LED version was built on a standard FR4 circuit board (fiberglass and epoxy construction) with conformal coating. Fiber core boards can absorb moisture over time, which can compromise the integrity of the circuit.

The new LED package is built on a MCB circuit board (metal core construction) with conformal coating. Aluminum does not allow moisture to penetrate the circuitry and the added benefit is immediate heat transfer from the LED chip. Heat is the enemy of the LED chip. Aluminum allows efficient transfer of heat and promotes added life to the LED.

How do I identify the new 2015 LED package?

Christen Hartman

Answer
The previous Integral Lighting LED version .20 was produced 07/2008 through 07/2015.

The new and improved LED version .40 is being produced from 08/2015 through now.

To identify which LED version…

  • Previous LED version .20 has 16 round phosphor dots (yellow) in the white ceramic holder.
  • New LED version .40 has 4 individual rectangular phosphor chips (yellow) in a cluster.

In addition to the look of the LED itself, our labels were updated with the correct wattage consumption to help identify which version you have installed. The wattage will be indicated on the fixture label (under the faceplate) and the box label.

How energy efficient is the new LED package?

Christen Hartman

Answer

Our new LED package is operating on 12vAC and is more efficient than our previous version. This new package will save you more money over the life of the fixture. The following is the energy consumption and annual estimated cost to operate per model…

  • IL300.xxx.xxx… .25 watt consumption… $0.05 annual cost
  • IL4.xxx.500… 1 watt consumption… $0.18 annual cost
  • IL6.xxx.500… 2 watt consumption… $0.36 annual cost
  • IL600.xxx.xxx… .50 watt consumption… $0.09 annual cost
  • IL18.xxx.500… 4 watt consumption… $0.72 annual cost
  • PL24.xxx.500… 3 watt consumption… $0.54 annual cost

For a better perspective, our IL6.xxx Xenon lamped fixture operates on approximately $1.98 annually.

These estimates of cost are based on 4 hours of operation per day and the average cost of electric as calculated by the USEIA. To learn more, please visit U.S. Energy Information Administration.

Can I use the previous version and new version together?

Christen Hartman

Answer
We have taken every measure to match the light output of the new version with the previous version. The color output remains consistent, however, due to the lumen maintenance factor (LM80), the LEDs may age at different rates.

The new upgraded LED version may age more slowly compared to the previous version. The LM80 has been improved and will maintain output consistency over its lifespan. You may not notice a variance upon installation, but it may affect the fixture’s output over a longer period of time. It may or may not be detected by the human eye, dependent on surface color and texture, but we do not recommend mixing the two versions on the same job.

We have reserved limited stock of the previous LED version to accommodate future add-ons to hardscape projects. Please discuss your project with your Authorized Distributor or call us directly to assist you with your order.

Is the color output consistent between versions?

admin

Answer
We have taken every measure to closely match the color output of our new LED package to our previous version. The optical performance of the LED, as measured by an integrating sphere, indicates that we are within 40-50 K of the previous color output (CCT).

The new package has improved lumen maintenance, which means the two versions will not age at the same rate. For this reason, it is not recommended to mix the new version with the previous version on the same installation.

We have reserved a limited stock of the previous version for warranty and service claims.

What is LM80 and how is it tested?

Christen Hartman

Answer
LM80 is a third party testing to report lumen maintenance.

LM80 specifies testing up to 60,000 hours. TM21 recommends a method for projecting the results of the LM80 tests beyond 60,000 hours to arrive at a reasonable estimate of LED “life.”

What is Lumen Maintenance?

  • LED emitters typically do not burn out or “die” in the practical life of any LED product; they fade in intensity. So the concept of “lamp life” has been replaced by the concept of “lumen maintenance.”
  • Lumen maintenance is generally a prediction of the number of hours an emitter will operate before it fades below a usable level of intensity. Currently, most lumen maintenance reporting assumes that dropping below 70% intensity is the end of life for an LED emitter.
  • LED lumen maintenance is typically reported as a total number of hours with a “B” number and an “L” number. ETC rates its LED fixtures with a lumen maintenance value of 50,000 hours (B50, L70). This is a very common rating in the LED fixture industry. This indicates that after 50,000 hours of use, 50% of the LEDs tested (B50) will fall below 70% of their initial lumen output (L70).
  • These metrics indicate the probability that a single LED will fail lumen maintenance under precise test conditions, not necessarily a system of LEDs, or the drivers and power supplies used in a luminaire.
