Q1: Does Dualrays have the ability to do independence and development ?
RE: Our engineer department have 12 people. We have the research and development capability. We also collect regularly each customer feedback. We have product improvement and new product development.
Q2: LEDs are more expensive than other lighting options,why ?
RE: LEDs can operate as stand alone devices,but when grouped or clustered they require additional steps to operate properly. LEDs need proper components such as a circuits can be designed rapidly, but to ensure that they operate correctly and for long periods of time they require testing.
Q3.What’s the meaning of “Beam Angle “?
RE: The spread of light from a luminaire. For example: a fitting such as a low bay ,which is closer to the floor,will have a wider beam angle to illuminate a given floor area while a high bay fitting will have a narrower beam.
Q4.How do we explain “CRI” ?
RE: A measure of the degree of colour shift objects undergo when illuminated by the light source as compared with those same objects when illuminated by a reference source of comparable colour temperature. The reference source has a CRI of 100.
Q5.What’s CCT(colour temperature) ?
RE: The description used to describe the effect of heating an object until it grows incandescently. The emitted radiation, and apparent colour, changes proportional to the temperature; easily envisioned radiation, and apparent colour, changes proportional to the temperature; easily envisioned ,when considering hot meal in a forge that glows red, then orange, and then white as the temperature increases.
Q6.Do you know “dali “?
RE: Digital addressable lighting interface (DALI) is a trademark for network-based systems that control lighting in building automation.
