Can 120V, 230V, 240v LED Strips or LED Rope Lights be dimmed?

You can use a magnetic dimmer or Triac dimmer, but the results are often mixed and unsatisfactory.  LED Lights that work with these dimmers have an integrated circuit built into the lamp that adjusts to the voltage.  Line voltage Linear LED lighting uses a rectifier to change the AC (Alternating Current) sine wave to DC (Direct Current) square wave to remove the visible frequency from the light source.  If the light strip creates enough of a load on the Triac or Magnetic dimmers they will work fine, if not they will dim in stages and likely flicker.  This can be fixed by adding an incandescent light to the circuit.

Another option would be Digital Lighting Systems line voltage dimmer packs. We have not tested them, but have heard good feedback.

Can I connect multiple LED strips to one PSU?

Yes, it is perfectly acceptable to connect multiple LED strips to the same PSU (power supply unit). The thing to keep in mind, is that every PSU has a wattage rating, which must not be exceeded. In fact, the common practice is to oversize power supplies by 10-15%. For example, if you were loading a PSU with four LED strips, each expected to draw 20W (4 x 20W = 80W), you should a power supply rated for 90-95W. In this case, an HLG-100-24V, rated for 96W, would do nicely.

IP rated: what does IP68 mean?

Our Vivid line of linear LED lighting is IP rated (IP68 to be exact) when used with properly-assembled compression connectors. So what dos this mean?

The IP Code, as laid out in IEC standard 60529, describes varying levels of protection against intrusion. In the case of lighting, we are concerned with intrusion of dust and water, which could compromise the working of the electronics.

In an IP68 rating, the 6 means “dust tight”, meaning the fixture is completely protected against dust. The 8 means it is protected against “immersion beyond 1m”, meaning the fixture has withstood submersion deeper than 1m of water under test conditions.

Pantone numbers for single color Vivid S?

The Pantone numbers for Vivid S single colors are:

Red – 711C
Green – 3278C
Yellow – 103C
Blue – 2103C

Quick connect leads: are they standard?

Not as a standard, no, except on samples. We can provide quick connect leads on factory orders, but there will be an additional charge.


RAL codes for single color Vivid S?

The RAL codes for single-color Vivid S are:

Red – RAL 3028
Green – RAL 6024
Yellow – RAL 1012
Blue – RAL 5000

Seamless linear LED power feeds vs standard.

We carry two basic types of power feed accessory (for our Vivid linear LEDs. The standard screw-on type (faster lead time), and a special factory-assembled type, perfect for seamless linear LED applications.

Regular power feeds are tool assembled and a bit bulky, they are however the fastest to obtain. The seamless power feeds are manufactured when ordered, so exact lengths must be provided during the ordering process. The seamless power feeds can not be modified after they are produced, so it is vital to verify all measurements and lengths before ordering. The standard connectors are available as end-exit (shown in left-hand photo) or bottom-exit. The seamless, factory-assembled connectors are available as bottom-exit (shown in right-hand photo), side-exit and end-exit.

What are tunable/dynamic white CCT LEDs or LED fixtures?

Tunable white LEDs are light packages that combine individual chips to produce a range of CCT from warm white and cool white. Special dimmers and control equipment is needed to properly operate a tunable or dynamic white LED light fixture.

What materials are the mounting hardware made of?

a. The standard 1m (40″) mounting channel, our most popular mounting hardware, is made of oxidized aluminum. The 2″ mounting clip is made of the same material, cut short.

b. The self-locking mounting channel, essential mounting hardware for vertical or upside-down installations, is made of the same oxidized aluminum as the standard mounting channel with the addition of special stainless steel 304 locking clips. Also available in a 2″ mounting clip version for curved installations.

c. The plastic mounting channel is made of a plastic polycarbonate, with UV inhibitors to prevent degradation by UV light.

Why are there left and right power feeds?

The left vs. right have to do with the fact that the LED circuit board is off-center, so you need a slightly different power feed for either end of a single piece. Say you had a 10ft piece and wanted wire coming out of both ends; if you tried to connect two left-power-feeds, one end would not seat properly and you would have a large gap where water could get in. You would need a left for one end, and a right for the other.

Will GLLS LED Lights work with Programmable Logic Controller (PLC)

Yes. We have several different options for dimming, sequences and on/off using PLC. Please contact one of our sales reps for more details.
