Luminus Gen4 CXM32, 3500K 80 CRI COBs have arrived.
Highest efficiency COBs of 2019.
On 93% efficient dimmable XLG-150 drivers. Set to the nominal current of 122.9W, on a huge 400mm x 200mm x 40mm heatsink.
The COB is able to be run up to a whopping 284W with adequate cooling. (We don't recommend you try - that would require water cooled copper)
We have a few options for lenses/reflectors.
1. 120 degree angle BJB COB mini-reflector,
2. 45/60/90 degree angle glass lens
3. Ledil Stella 120 degrees (limited stock)
Note: out of 90 degree lenses. 120 degrees advised now.
We will default to the BJB holder. Let us know in an email if you prefer a glass lens.
COBs offer a higher intensity of light, over a smaller area than quantum boards.
The new Gen 4 Luminus COBs are an efficient new COB, released in 2019, with efficiency greater than Cree CXB3590, Bridgelux Vero29 and Citizen CLU48/58.
Recommended vegging height of 60cm, flowering height of 35-45cm, with a 90 degree glass lens. Migro reckons the COB at 115W is good for 60x60 flowering and 90x90 vegging.
