How do I size a transformer for my lighting installation?

admin

Answer

Calculate the total wattage of all lighting fixtures that will be hooked up to your transformer. The total wattage will be the minimum required output of the transformer.

When sizing a transformer for an LED installation, use the wattage consumed by each lamp, not the wattage output or brightness equivalent.

The industry recommends utilizing 80% of your transformer’s capacity for optimal system life.

Example: a 60 watt transformer would be ideal for the lighting installation below.

How do I mount a low voltage transformer?

admin

Answer
Your power supply should be mounted at least 12 inches above ground level. Many transformers are not completely sealed and should have that clearance according to UL 1838.

Do I need to take voltage readings with electronic transformers?

admin

Answer
It’s not necessary. Our Electronic LED Transformer automatically supplies 12 volts AC and adjusts for the amount of demand. The actual output will vary depending on the number of fixtures but will not exceed 12 volts.

When utilizing a magnetic transformer, it is imperative to take voltage readings. As magnetic transformers do not regulate voltage, accurate readings are necessary to ensure your fixtures perform as warranted.

Can I mount my low voltage transformer inside?

admin

Answer
No. Generally speaking, low voltage transformers are listed and labeled for “Outdoor Use Only.”

If your installation requires an indoor transformer, consult your local electrical codes… you may be able to purchase a low voltage power supply locally for that specific use. Remember that if you are using a photocell, you may have to make other provisions for controlling the outdoor lighting.

How many LEDs can the electronic transformer handle?

admin

Answer

Our Electronic LED Transformer typically powers 1 to 20 Integral Lighting LED fixtures on a cable run of less than 100′. If your job requires a larger quantity of fixtures, or a longer cable run, please call our office at 800-861-1364 to discuss your project with us. We will help you determine which transformer will work best for your lighting.

How close can an LED be mounted to the electronic transformer?

admin

Answer

Fixtures can be positioned within 1′ to 50′ of the receptacle. Our Electronic LED Transformer automatically adjusts the load, therefore eliminating any worry of overpowering a fixture mounted too close to the power supply.

Do I need to use low voltage cable with the electronic transformer?

admin

Answer
Yes. 12/2 gauge low voltage cable is recommended.

Can I use your electronic transformer to power AC and DC lights?

admin

Answer

Our Electronic LED Transformer delivers 12 volts AC. It is specified for AC fixtures only and is compatible with all Integral Lighting 12vAC LED fixtures. If you purchased fixtures manufactured by companies other than Integral Lighting, please consult the manufacturer prior to installation.

Do fixtures dim with further distances (as with magnetic transformers)?

admin

Answer
Yes. Longer runs of cable still affect the transmission of voltage. If this is the case and you require a longer run or the lights are too dim, consider a magnetic transformer in lieu of the electronic transformer.

Does the electronic transformer require a minimum load to turn on?

admin

Answer

In general, electronic transformers typically require a minimum load to turn on. Our unit is designed to power a single fixture if that is what your job requires.

With that being said, it also has limitations. This transformer is designed to power 1 to 20 Integral Lighting LED fixtures on cable runs up to 100′. For larger installations, consider using a magnetic transformer or call 800-861-1364 to discuss your project with us.
