My perspective is as a lighting designer and product developer in LED for commercial lighting for nearly 20 years so as a rule of thumb keep it simple . So I'll keep it brief also , where possible take your plans if you can to a lighting specialist /retailer and they can pinpoint your lights FREE for you and possibly do a deal on a house lot of lights also. If you are looking for uniform lighting not too many shadows and balanced light a very general rule is symmetry, in a square room 4 down lights are more than enough and possibly too much if of high light output. For domestic applications most lights sold by a reputable retail store will do a great job in your home , do chose a wide beam for general lighting 60 degrees to 90 degrees and for ambience a warm colour 2700K-3200K range and make sure dimmable so you have some control to set a mood as required.(make sure your dimmers used are matched and suited to the brand of lights you buy) Now LEDs are measured in wattage (so power consumed if efficiency is of importance to you the lower wattage the less power consumed) and if not so much a reasonable quality LED down light will produce about 60-70 or more Lumens (a light measurement)per watt of energy used. So a reasonable assumption is 10W down light is about 600-700Lumens output fair and reasonable for 2.4/2.7 meter ceilings and don't forget if too bright you can dim them. Now CRI of 70-80 is more than acceptable for a domestic installation unless you do a lot of colour matching or reading fine prints or similar work requiring more precise colour renderings of fabrics and such, and yes higher CRI (colour rendering Index)products will cost a lot more at this stage. For heat loss or fire issues as someone mentioned before or raising your house energy efficiency rating and stopping draft heat loss from the gaps in down lights if you don't need to tilt them (gimbal down lights) get fixed sealed units or Gimbal units within a fire rated canister or sealed casing just ask your friendly retail lighting person. Yes lighting can be a complex project if you get caught up in all the technical hype that is sometimes used to show how smart the sales person is rather than trying to find the right solution for your application. Lighting done right can set so many moods and frame your home to be a comfortable retreat . Re: Led downlighting 11Apr 06, 2015 11:09 pm I decided on this product for the downlights I intend to install. I can insulate right up to the housing and the downlight still gets ventilation. http://www.arrowform.com.au/downlight-c ... ight-guard |
