How long is the lead length on a normal strip light?

Every strip light is made with 6" wire leads on both ends of the 16.4' reel of lights. This allows you to cut the strip light anywhere and utilize both ends for your project.

Should I choose Standard Brightness or Ultra Bright?

This is a personal preference and depends on your application. If you generally like your light levels high or more bright or if you are trying to light a larger area, go with Ultra Bright as the light will spread farther. If you generally like a dimmer light, go with Standard Bright. For example, Standard Bright will still be bright enough to light a counter as under-cabinet lighting and makes a nice accent lighting for cove lighting. However, if you want more of a task lighting at your counters or you want to wash a wall with light, you will likely be happier with Ultra Bright. If you are unsure, go with Ultra Bright and use a dimmer to allow you to choose your own brightness once installed.

Do I need Waterproof, Water Resistant or Non-Waterproof?

To select the right LED strip light, consider your application. If it is going to be used outdoors where it will be exposed to rain, humidity or moisture go with the Waterproof. The Waterproof strip lights are completely encased in silicone and can be submersed under water. They are also more resilient to heavy traffic or abuse because of this protection layer. If it will be used indoors near a sink or in a location where it might occasionally get splashed, or under a covered roof outdoors where it will be protected from most moisture, go with Water Resistant. If you are using it indoors and there is no chance of direct water or moisture exposure, the Non-Waterproof will be your best bet.

What lengths are available? What if I need longer than 16.4'?

All of our strip lights are manufactured to 16.4' (5 Meters) but they can be daisy chained together. For high volume, special orders can be made custom to length. Call or chat for more information. For specific questions about your application, feel free to chat with one of our LED lighting experts.

Can I connect multiple strip lights together?

This depends on the model of strip light you select but this is an option with several models. See the product specifications for maximum run length. Also, the distance you can run will depend on the voltage you select. If you plan to run more than 16 feet select 24VDC strip lights. If you plan to cut your strip lights and are looking for pre-made connectors to avoid soldering, check out our Strip Light Connectors and make your install easier.

How do I connect my strip lights to the power supply?

On the strip light, there are two wires; a red wire and a black wire. The red wire is the line(+) wire and the black wire is the neutral(-) wire. Your power supply will also have a line(+) and neutral(-) wire. Connect the corresponding wires together using standard wire nuts or splice/crimp connectors.

What gauge wire should I use to run between my strip light and my power supply?

This depends on the distance between your strip light and the power supply. We generally recommend using between 18ga and 14ga stranded wire. Longer distances require larger gauge wire. Always consult a wire gauge chart to determine the correct size wire for your application.

Which voltage option should I choose?

12VDC: 12 volt strip lights are popular for battery powered applications like automotive, motorcycle, boat/marine applications, or anywhere where you are connecting to a 12VDC supply. Our 12V strip lights also typically have the cut points closer together. Some applications may require a separate 12VDC power supply!

24VDC: Our 24 volt option is the most popular for residential and commercial applications. 24VDC is a safe low voltage, dims the best, usually runs farther without voltage drop issues, and is the most stable and reliable voltage for your aspectLED strip lights. Requires a separate 24VDC supply!
