FAQ

Below you'll find answers to the questions we get asked the most about for all Lumino Lighting Products and designs.

What is ColorCORE® technology?
ColorCORE® is Lumino’s proprietary phosphor-core technology that converts single frequency 450nm blue light into full spectrum, visible white light with strong rendering of reds, blues, greens, oranges and yellows. ColorCORE® High CRI stands out with excellent colour rendering of up to 95 Ra8 and 92 Ra14 thanks to high values across the entire R1-R14 colour palette.
What is OPX™ Optical Performance?
OPX™ Optical Performance provides outstanding light output ratios and diffused reflectance.
What colour temperatures are available?
ColorCORE® products are available in 2000K, 2400K, 2700K, 3000K, 3500K, 4000K and 4500K
What is the warranty period for Vector products?
Lumino offer a 5 Year Limited Warranty subject to registration and warranty terms and conditions.
What is the life expectancy of Vector products?
L70 >60,000 hours for ColorCORE® products. LM80 for ColorCORE® products is available on request.
How and where are Vector LEDs photometrically tested?
Photometric data published by Lumino is measured in-house and verified by independent testing and certification laboratories including NPL and LUX-TSI. Vector products are tested to LM79 standards where required.
Can I mix different colour temperatures within one Vector profile?
Yes, as a custom-build, we can accommodate one, two or three strips within the V36S, V36I and V36R profile and one or two strips within V20S. Each strip can be a different colour temperature or even a different power rating.
Do Lumino build custom made products?
If the quantity makes it feasible we will consider producing custom made products to suit your requirements. Let us know what you need on +44 (0) 1279 635411.
What are the minimum and maximum lengths available?
Most Vector products are available in multiples of 100mm up to 2000mm (see data sheets for exact lengths). Custom made longer lengths may be available depending on the specification. Let us know what you need on +44 (0) 1279 635411.
What is the maximum cable length I can use from the driver to the Vector product?
The cable length between the driver (including any dimming interface) and Vector product varies by product type, load etc - see the product’s wiring guide for confirmation. The maximum cable length is normally 10 metres; this is due to EMC regulations (electromagnetic interference). There is a work-around that allows longer cable runs however for all cable lengths exceeding 10 m, EMI emissions have to be verified in the application. When EMI emission exceed the allowed levels it may be possible to reduce the EMI emissions by using ferrite cores. If using cables at least 1.5mm2 section, by clamping ferrite cores to the cables electromagnetic interference is reduced. TDK provide such a ferrite core, part number ZCAT3035-1330 - a pair of these cores would need to be clamped around each output from the driver and dimming interface. Such modifications must be independently tested for EMI.
Fault: LEDs are flashing on and off.
This is most likely caused by an overloaded driver. Check you have not exceeded the maximum rating for the driver. e.g. Using 10 metres of V10S-12 is a load of 10 x 12w = 120w therefore a 100w driver will be overloaded and will continuously auto-shutdown (depending on driver model) and restart causing the LEDs to flash.
Fault: LEDs do not come on at all.
This could be caused by a number of issues. Check the wiring circuit, you should be measuring the appropriate voltage at the power feed cable into the LED profile. If there is no voltage a loose cable could be the cause of this problem. Alternatively a dead short across positive and negative will cause this issue as could reversed polarity. If you have checked and eliminated all of these issues, swap out the driver and see if the problem persists.
Fault: LEDs flicker on and off.
If the LEDs flash slowly and regularly this issue is probably an overloaded driver (see above). If it is an intermittent flicker there is most likely a loose connection somewhere in the circuit.
Fault: Powering on the LEDs causes the MCB to trip off
Most constant voltage LED drivers have a high inrush current when first powered on. This inrush current can be many times the normal operating current but only for the first few milliseconds at power on. Check the maximum inrush current of the driver you are using and ensure you use a suitable MCB. Type C MCBs are normally suitable where 2 or 3 drivers are used on the same circuit. Where 4 or more drivers are being used on the same circuit, an inrush suppressor may be required in addition to a suitable MCB.
