Olight doesn’t buy tint binned emitters like Fireflies does. You end up with a tint lottery like Zebralights but to a lesser extent in most cases. The first H2R Nova NW I bought had one of the best tints I’ve ever seen. The 2nd one I bought turned out horrendously green so I returned it right away. Here are the measurements I took of this heavily used H2R with battery probably not full. The DUV approaches 219B sw45k levels and is slightly rosier than even the 5A/5D binned Cree emitters I’ve seen.
Turbo, 2215 lumens, 4231K, DUV –0.0060, CRI 74.8, R9 –2.8, R12 48.4, Rf 69, Rg 100
Top of Ramp, 526 lumens, 4081K, DUV –0.0030, CRI 75.3, R9 –3.9, R12 46.8, Rf 71, Rg 99
The Olight Seeker 2 Pro also has an excellent pure NW tint.
But really Olight doesn’t try or care about getting good tint. It’s really just a matter of luck. People need to start letting them know we want warmer tints and non green tint. I’ve sent them many emails before but I’m just one customer. Maybe posting on their Facebook page would help.
