Frequently asked questions
How many lux does highways / arterial (group a) need?
Indian practice (IS 1944) recommends 30 to 40 lux maintained on the task plane with uniformity of at least 0.4. New installations should target 20–30% above the maintained value to allow for lamp depreciation and dirt.
What mounting height is typical for highways / arterial (group a)?
Around 12 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 Street 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.
