What should I check before buying 110V Site Lighting?

The short answer

Check seven things before you buy: the IP rating (IP65 for outdoor and wet areas), the IK impact rating (IK08 or higher on site), real light output in lumens from a spec sheet, emergency duration (3 hours is the usual site specification), the cable type (arctic grade or rubber, not ordinary PVC flex), CE or UKCA marking with the voltage on the label, and the warranty and whether parts can be replaced. Cheap lights often fall down on two or three of these, and a light that fails on site costs far more than the difference in price.

The checklist

CheckWhat to look forWhy it matters
IP ratingIP65 for outdoor, wet or dusty areas; IP44 at least for sheltered useWater and dust are the main reasons site lights fail
IK ratingIK08 or higherSite lights get knocked by ladders, materials and plant
Light outputLumens on a spec sheet, not just wattsTwo 100W lights can give very different amounts of light
EmergencyStated duration, usually 3 hours, and the output in emergency modeStairwells and escape routes must stay lit when the power fails
CableArctic grade (marked with a code such as 3183YA) or rubber H05RN-FOrdinary PVC flex can crack in the cold
MarkingsCE or UKCA, voltage and maker on the labelNo marking, no comeback
Warranty and partsA real warranty and replaceable partsA light you can repair costs less over its life

1. IP rating: water and dust

The first number is dust (6 means dust-tight), the second is water (4 is splashing, 5 is water jets). IP65 is the sensible minimum outdoors and in buildings that aren't yet watertight. Our Floodlights and LED Bulkheads are IP65.

2. IK rating: knocks

IK08 means the light withstands a 5 joule impact, roughly a 1.7kg mass dropped from 300mm. Our Floodlights and LED Bulkheads are IK08.

3. Light output: lumens, not watts

Watts tell you what a light uses, lumens tell you what it gives. Ask for the spec sheet. Our LED Floodlights give about 120 lumens per watt, and our 2ft Site Fittings give 3,200 lumens from 27W. Use the lighting calculator to turn lumens into the number of lights you need.

4. Emergency lighting

Check how long the emergency mode lasts and how bright it is. Our Emergency Festoon gives 3 hours at 10% of normal output when the mains fails, and the 2ft Site Fittings come with a built-in emergency module. See how to light a stairwell.

5. The cable

Site leads need cable that stays flexible in the cold: arctic grade flexible cable or rubber cable. Industry testing has found ordinary PVC flex dyed yellow and sold as arctic, which can split in cold weather and expose live conductors. Our 2ft Site Fittings are pre-wired with Arctic Cable and our Floodlights have a rubber H05RN-F lead. More in why one Arctic Cable costs more than another.

6. Markings and paperwork

Look for CE or UKCA marking, the voltage and the maker on the label, and a spec sheet you can download. If a light has none of these, you have nothing to go back to if it fails.

7. Warranty and repairs

A longer warranty is a sign the maker expects the light to last. Our Floodlights and switchable Bulkheads carry a 3-year warranty, and our 2ft contract fittings have a replaceable emergency module, battery, driver, case and diffuser, so they can be refurbished rather than thrown away.

Questions we get asked

Is IP44 good enough for Site Lighting?

Under cover, yes. Outdoors, or in a building that isn't yet watertight, choose IP65 so water jets and dust can't get in.

What does IK08 mean?

It's an impact rating: the light withstands a 5 joule impact, about a 1.7kg mass dropped from 300mm. IK08 or higher suits site use.

Why do some site lights cost so much less?

Usually because something on the checklist has been left out: lower real lumens, a lower IP or IK rating, ordinary PVC cable instead of arctic, no emergency duration stated, or no replaceable parts and a short warranty.
