Frequently asked questions
Which mounting options are possible?
Ceiling pendant (chain or rigid pendant), flag bracket or free-standing on a floor or pole base. For an 18 cm display, ceiling suspension in atriums is the most common choice.
What is the power consumption of a double-faced 18 cm display?
Significantly higher than a single-sided model; see the datasheet for the exact spec. AC power is the recommended choice for this class; PoE is usually not sufficient.
Do both sides synchronise to the second?
Yes, a single internal NTP circuit drives both sides at the same time. There is no perceptible offset between front and back.
What is the lead time for this product?
Standard lead time is 8-10 weeks from Masterclock USA. Daylight bv stocks the most common references in Ghent. Contact us for current availability and any rush options.
What warranty do you get on this product?
1 year Daylight warranty + 4 years extra Masterclock warranty on parts and labour (5 years total), via Daylight bv as authorised Masterclock distributor. Carry-in for customers in the EEA, on-site available by prior arrangement. See five-year warranty.
