MNBS1191 – IP54 Adjustable Recessed Downlight for Soffit and Outdoor Ceiling Lighting

Power:
Indicates the power consumption and electrical requirements of the light.
"1X7W/350mA/Max.19V" means one LED unit consuming 7 watts, drawing 350mA current, and operating at a maximum of 19 volts.
"1X10W/500mA/Max.19V" means one LED unit consuming 10 watts, drawing 500mA current, and operating at a maximum of 19 volts.
CCT (Correlated Color Temperature):
Refers to the color of the light emitted.
"2700/3000/4000K" indicates available color temperatures: 2700K (warm white), 3000K (soft white), and 4000K (cool white). 
Flux:
Represents the luminous flux, or the total amount of visible light emitted.
"630lm/960lm" indicates the light output in lumens for the 7W and 10W versions, respectively.
CRI (Color Rendering Index):
Measures how accurately the light source renders colors compared to natural light.
"≥98" signifies a very high CRI, meaning colors will appear very true to life under this light. 
Cutout:
Specifies the diameter of the hole required in the ceiling for installation.
"Ø83mm" means a circular cutout with a diameter of 83 millimeters.
Beam angle:
Describes how widely the light spreads from the fixture.
"15° 24° 36° 50°" indicates various available beam angles, allowing for different lighting effects from narrow spotlighting to broader floodlighting. 
Symbols:
CE: Conforms to European safety, health, and environmental protection standards.
House with arrow: Indicates suitability for indoor use.
III (Class III): Denotes a Class III electrical appliance, meaning it relies on safety extra-low voltage (SELV) for protection against electric shock.
Parallel lines with arrow (1-35mm): Likely indicates the suitable thickness of the mounting surface (e.g., ceiling material) for installation.
IP54: Ingress Protection rating, where '5' means protection against dust ingress and '4' means protection against splashing water from any direction.
