10K feet is the maximum altitude our equipments support as well.

Our typical PDs support operation up to a maximum altitude of 10k ft (3048m).
Jeff requested today to define what the maximum altitude is where PDs are still supposed to work. I've requested this information, and we follow IEC 60721-2-3 which defines operating altitudes from 0m to 2000m altitude for our standard lighting fixtures.
