hi new mac :jointsmile:

i do have 660nm in mine....50% of the diodes are 660nm

welthink will make lights to customers specs if the order is large enough....and i have found a few people selling lights cheaper that are only 630nm/460nm

Old mac ~ no offense taken but thank you for the apology...i knew the comment was not directed at me....just clarifying where my lights were made :jointsmile:
