Hi Tim, yes 900 lux seems excessive, reduced overhead with task lighting would be better for all involved and probably more cost efficient. I use overhead fluorescents that are always off unless I am in the lab for extended periods, I have daylight,(windows) which I find are preffered for colour matching as well as incandecent for task lighting.Hope this helps, James Engelbert Conservation Centre Historic Sites Edmonto780-415-4422 [log in to unmask] -----Original Message----- From: Timothy McShane [mailto:[log in to unmask]] Sent: Thursday, February 06, 2003 9:35 AM To: [log in to unmask] Subject: Lighting levels in conservation workspace Hi all. We're in the process of finalizing plans for a new facility to open in 2005. The architect's lighting consultant, after discussions with other museums, has recommended a light level of 900 lux in the conservation lab. I can see the need for occasionally requiring high light levels (ie., proper colour renderings, etc.), but 900 lux for overall lighting seems excessive. We have had some suggestions, such as lower ambient light with specific task lighting (ie., those magnifying lamps on the adjustable arms; above-counter lighting, etc.), or having the room lights on two banks, so that when both are on we have the 900 lux, and with only one on we have around 450-500 lux. I've never worked in a space specifically designed for conservation--what type of lighting do those of you with conservation labs have? Is 900 lux excessive, or do you regularly require that much ambient light? Would office-level lighting (around 500 lux) with task lighting be sufficient? Thanks for any thoughts/anecdotes you care to share with me! ------------------------------------------------------------ Tim McShane, Assistant--Cultural History Medicine Hat Museum and Art Gallery 1302 Bomford Crescent S.W.
