Frequently Asked Questions

Here are some frequently asked questions that we hope will solve your answers quickly. If you have any questions you can call or email our team.

LED chips produce very little heat. However, the electronic circuit board that powers the LEDs does produce heat. For this reason Sunbound light bars are designed with an aluminum heat sink housing, which decreases running temperature and increase LED performance. The typical temperature range for crescent and pyramid frames should be from 90°-110°F. Groove and slim frames generate more heat due to the low profile design, so they can get up to 120°F. If LEDs are hot to the touch, they are being overpowered due to improper circuitry or a defective driver.

Yes. If the lights are connected to AC voltage, they will immediately be damaged and possibly cause a fire risk. If the polarity of the DC voltage is reversed, the lights will not work but will not cause damage. This is a common mistake, always double check to make sure positive (dashed line) and negative (solid color wire) are lined up correctly when troubleshooting.

The most common reason for lights not turning on is polarity. Unlike AC Voltage, DC voltage remains strict with polarity. Always make sure the negative and the positive terminals match up. Check to make sure your connections are correct

There could be several reasons why your lights are flickering. The most common occurrence is due to an incompatible dimmer switch, the minimum and maximum dimmer loads not met, or a defective driver. If you are using a dimmer not provided by Sunbound, ensure it is CFL/LED compatible. Also see dimmer switch specs for minimum load requirements. Check the output voltage of the driver, and ensure the output reads between 10V-12V without any load. Lastly, make sure all the wiring is correct. If excess flickering is still apparent, please contact technical support.

Ensure the driver is not overloaded. Always de-rate the driver 20% from its labeled rating. Ensure there is not a short circuit occurring. If the breaker continues to trip after reset then contact technical support as the driver may be defective.

Yes. If you are powering your lights with a dimmable transformer you must use an LED/CFL compatible dimmer switch, which connects from the AC 120V input into the dimmable transformer. We also have low voltage switching options available.

Our drivers are compatible with a range of dimmers from different manufacturers, depending on your driver model. Please contact our technical support team for a full list of dimmers that work with your specific model. If you are using a power supply that plugs into a standard outlet, then you will need an inline DC dimmer control. This can easily connect between the power supply and the first light bar. SunBound Lighting has several types of low-voltage DC dimmer switches. Please contact us for a full list of products.

Modern LED lighting comes in a varity of different colors to suit everyone’s tastes. Sometimed these colors are reffered to as “warm”, “cold” or “soft”. In order to accuratly refer to these different colors, Sunbound use the measureable industry standard of color temperature in degrees kelvin. These can be seen below in the 4 most common temperatures used at Sunbound. 

Both lights are energy efficient light sources that are much more efficient than the bulbs they replace. Here is a small list of the differences between CFLs and LEDs:

  • CFLs are the spiral tube like bulbs. They are really mini fluorescent bulbs with self contained ballasts. They contain a small amount of mercury. LED bulbs are the new style looking bulbs with heat sinks and round mini globes. They do not contain mercury.

  • You can replace a 22W CFL bulb with a 11W LED bulb.

  • LED lights are instant on, instant off. CFLs take 30 seconds to 1 minute to warm up after they are turned on

  • LED bulbs are not affected by turning them off and on. CFL bulbs are, as this will reduce their life
