Frequently asked questions
How many lux does drawing office / precision need?
Indian practice (NBC 2016 Part 8 Table 1) recommends 750 to 1000 lux maintained on the task plane with uniformity of at least 0.7. New installations should target 20–30% above the maintained value to allow for lamp depreciation and dirt.
What mounting height is typical for drawing office / precision?
Around 3 m is typical. Higher mounting needs more lumens per fixture or closer spacing to keep uniformity.
Which HiLums or Oreli fixture should I use?
LED Panel & Surface Lights are the usual choices. Use the bulk & customisation portal to enter your dimensions; it sizes lumens, wattage and quantity and lets you choose AC, DC or solar supply, CCT, surge protection and mounting.
