The Lumis LED product is available in either Lumis Mesopic Green or Lumis EcoWhite. Both light outputs are produced by a combination of green and red light outputs from the LEDs, with the latter featuring a greater red content to improve colour rendering. EcoWhite is therefore more appropriate in most locations, but where colour is not really important (cough, SOX), Green can be chosen, and is slightly more efficient due to the spectrum. Green is available in 8w, 14w and 22w sizes, and EcoWhite in 16w, 24w and 36w sizes. The products are supposed to be able to last for 20 years with <10% lumen depreciation and only basic cleaning cycles required. Suggested mounting heights are between 4m and 8m, and there is suggestion on the website that 36w LED could replace 70w SON.
In the Netherlands, there are projects that have seen 16w EcoWhite installed at 5m height (Dutch would normally use 24w PL-L at this sort of height), and 36w EcoWhite installed at 8m height. However, thanks to a discovery on
Davy's website, I discovered that Plymouth is trialling the 24w EcoWhite version on 5m columns lighting a footpath, replacing the previous 36w PL-L WRTL Libras. As a side note, why must councils insist on replacing new lanterns with new trial lanterns? Why can't they replace 30 year old lanterns with new trial lanterns and get better value for money?
