LED Strips

A: 5050 LED Light Strips have an LED diode size of 5.0mm x 5.0mm and the 3528 LED Light Strips have an LED diode size of 3.5mm x 2.8mm.

A: Brightness of the LEDs depends on the quality of strip you purchase, not the size of the LED. 5050 LED Strips would be a little brighter than 3528 LED Strips, but only because the actual diode giving off light is bigger on the 5050 LED.

A: Single and dual density refers to the amount of LED diodes per meter. For example, a typical single density strip has 30 LED diodes per meter while a typical dual density strip has 60 LED diodes per meter.

A: The DMX LED Strip comes equipped with a 5 Pin XLR Connector. You just connect that to a DMX to RJ45 Cable to use with your computer.

A: Our LEDs could easily react to music or sound with the help of lighting control software.

A: Yes, you can cut the strips into segments. Be sure to cut only on the designated points of the strip.

A: All single color LED Light Strips (including White variations) will have a “2 point connection”.

A: Cheap strips are great for low risk, or low budget jobs where quality doesn’t really matter. But if you have a high cost job, where your reputation depends on the performance of the products you install, you can be assured that our strips are thoroughly tested, and engineered for ultimate performance. Not to mention we offer full support and always answer calls and emails.


A: Your power supply may be under-powered for the application. A power supply with a larger current may solve the problem.

A: The LED-CON2-R2 has a refresh rate of 5.2kHz. This should help eliminate flickering.

A: kHz is the current frequency, also known as “Refresh Rate”. Electricity is not constant, it oscillates at different frequencies, depending on how the circuit is put together. The higher the frequency, the less flickering you will encounter with your lights.

A: Most USB ports will only provide 5V from a computer. These rating are not high enough for a 5m LED strip. We recommend using either a Lithium Polymer battery capable of producing the voltage you need or a 12V adapter.

A: There is currently no way to 100% waterproof a battery. Although it is technically possible to make a water resistant battery, we do not recommend attempts to waterproof a battery because the smallest amount of liquid may lead to severe damage for your battery.

A: The LED DMX Drivers need an external power supply. Depending on the amount of strip being used, power supply capacity may vary. In most cases, a 200W power supply will suffice.

A: You may not need an amplifier if you put power source in the middle and go out left and right with 5 meter runs.

SIRS-E Wireless DMX

A: Unfortunately these Transceivers and Receivers are made for DMX signals not audio.

A: You won’t drop DMX signal as long as you don’t go past 2000FT of daisy chain cable.

A: These wireless DMX units will work great with moving heads, as long as they run on DMX512.

A: The anyDMX Wireless DMX Transceiver can control up to 512 channels at once, which can be multiple colors at once.
