As of right now I am in need of a replacement LH351D 4000K High-CRI emitter to test the lantern using four to compare that configuration over the two-LED set up. DO any one have any sources where i could get one?
Looks like you’re good for now, but Digi-Key actually has 8 varieties in-stock with no minimum. Different CRI’s (70-80) and CCT’s (3000-5700) available. Link
My name is cu42 and I approve of this message!! high CRI fan here.
I never put much thought into whether any high cri could be more efficient at medium outputs since as a newb I am always focused on the max numbers.
I was originally thinking the warmer 3k was the way to go for a camp lantern, but now wondering if high CRI at 4k would be more desirable than lower cri warm tint? Is there even such a thing as warm high cri?
Last I checked, daylight tends to be around 5500K mid-day, but it gets warmer in the morning and evening as the sun gets low in the sky. At sunrise/sunset it can be below 2000K. Moonlight tends to be around 4000K, but is generally too dim to activate cones for color perception.
