Specifications:
The catalogue details various lighting products under the 'Oty light' series by Nemo. Key specifications include IP20 rating, flicker rate of less than 20%, and a color rendering index (CRI) greater than 90. The lights operate at 220-240V with a power consumption of 9.5W and are dimmable using IGBT or TRIAC.

Product Variants:
The lights are available in multiple color combinations, including Black/Copper, White/Copper, Blue/Copper, Green/Copper, Rose/Copper, and Red/Copper. Each variant offers a nominal lumen output of 710 and a beam spread of 24°.

Inclusions and Exclusions:
The catalogue specifies whether drivers, transformers, and bulbs are included or excluded with each product. It also outlines the protection levels against solid objects and water, ranging from no protection to dust-proof and water jet protection.

Standards and Compliance:
Products comply with European Commission rules and are classified under different safety classes (I, II, III) based on insulation and earthing requirements. Class I requires earthing, Class II uses reinforced insulation, and Class III operates at low voltage without earthing.

Technical Parameters:
The document explains technical terms such as MacAdams step, which indicates the color deterioration level of LED lights, with step 3 being the lowest. It also defines lumen as the unit of light flux and lux as the unit for lighting a flat area.

Additional Information:
The catalogue includes a vademecum section that provides further technical insights into lighting parameters like CRI and CE compliance.
