The product sheet states the actual power and the protection rating to compare.\"}},{\"@type\":\"Question\",\"name\":\"Is 1000 lumens good lighting?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"It depends on what needs to be seen. An output of this order is enough to walk around, mark out a corridor or light a workstation up close, but becomes tight for reading a detailed plan or working at height. The distance between the source and the area matters as much as the output.\"}},{\"@type\":\"Question\",\"name\":\"How many lumens are needed for a good floodlight?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"There is no single value: it all depends on the area, the mounting height and the fineness of the work to be done. Think in illuminance on the ground, not raw lumens. Two moderate, well-aimed sources are better than one badly placed source.\"}},{\"@type\":\"Question\",\"name\":\"What is the best brand of LED floodlight?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The brand matters less than three verifiable elements: a protection rating suited to the exposure, a solid fixing and a data sheet consistent between power, output and colour temperature. A stated output inconsistent with the power is a warning sign.\"}},{\"@type\":\"Question\",\"name\":\"What is the difference between 3000 K and 4000 K?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"3000 K produces a warm white light, pleasant in a living room. 4000 K produces a neutral white light, with more contrast, which renders colours better and tires the eye less during prolonged reading. On a site, 4000 K is the most frequent choice.\"}},{\"@type\":\"Question\",\"name\":\"Which quality outdoor light string should you choose?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Favour an IP65 rating, clean seals and connections that stay dry, a flexible cable of sufficient cross-section, and well-spread light points. An outdoor light string is judged on how it holds up over time, not on the number of functions advertised.\"}},{\"@type\":\"Question\",\"name\":\"Can a site light string be hung on scaffolding?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes, provided the cable is never used as a load-bearing tie and hooks or clamps fixed to the pipe are used. The cable must stay free, without rubbing on an edge, and the power supply protected from water spray.\"}}]}]}\u003c\/script\u003e","products":[],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/8598\/2228\/collections\/designix-entete-guirlande-de-chantier-v1.jpg?v=1793054067","url":"https:\/\/designix-lighting.com\/collections\/site-light-string.oembed","provider":"Designix","version":"1.0","type":"link"}
