What are they spending now on getting blown bulbs replaced, does the company call out electrician to do it?

How about motion switches?]]> Office lighting https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9294&Focus=289715#Comment_289715 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9294&Focus=289715#Comment_289715 Sun, 23 May 2021 11:59:49 +0100 djh Office lighting https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9294&Focus=289717#Comment_289717 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9294&Focus=289717#Comment_289717 Sun, 23 May 2021 13:17:24 +0100 tony Office lighting https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9294&Focus=289720#Comment_289720 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9294&Focus=289720#Comment_289720 Sun, 23 May 2021 15:48:38 +0100 djh Office lighting https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9294&Focus=289732#Comment_289732 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9294&Focus=289732#Comment_289732 Mon, 24 May 2021 09:26:46 +0100 WillInAberdeen
Is that really what they were hoping? Or do they need replacing anyway, for looks or for emergency lighting?

Electricity is dramatically less carbon-intensive than it was even a few years ago, so there's less environmental benefits now from scrapping and replacing existing fittings. Just avoid halogen downlighters.]]> Office lighting https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9294&Focus=289733#Comment_289733 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9294&Focus=289733#Comment_289733 Mon, 24 May 2021 10:31:27 +0100 djh Posted By: WillInAberdeenTony, if they replace fluorescents with more fluorescents or LEDs, they won't save electricity/carbon/money.
I understand what you're saying, but a modern T5 with an electronic ballast may be twice as efficient as an old T12 with magnetic ballast. LEDs can approach the efficiency of a T5 fitting.]]> Office lighting https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9294&Focus=289744#Comment_289744 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9294&Focus=289744#Comment_289744 Mon, 24 May 2021 21:38:29 +0100 tony
