For lantern with no directional beam needed, I suggest 757 LEDs. Depending on the space available you can populate lots of them to get very high efficiency at much cheaper price. The options are.

A.
NF2W757GV3F1:
- R8000: 2000K, 2200K, 2700K, 3000K, 3500K, 4000K, 4500K, 5000K, 5700K, 6500K
- R9050: 2700K, 3000K, 3500K, 4000K, 4500K, 5000K, 5700K, 6500K
Note: $0,1/pc. Very efficient at extremely cheap price

B.
NF2L757GF1:
- R95: 2700K, 3000K, 3500K, 4000K, 4500K, 5000K
NF2W757GF1:
- R95: 5000K
Note: $0,3/pc. Priced very close to Optisolis, CRI slightly higher than R9080 unlike Optisolis, they can be mixed freely

C.
NF2L757GF1 (Optisolis):
- R95+: 2700K, 3000K, 3500K, 4000K
NF2W757GF1 (Optisolis):
- R95+: 5000K, 6500K
Note: $0,5/pc. CC and WW can’t be mixed in parallel. Currently, the highest possible CRI for LED

D.
NVSLE21AT
- R9080: 2000K, 2200K, 2700K, 3000K, 3500K, 4000K, 4500K, 5000K, 5700K, 6500K
NVSWE21AT
- R9080: 5000K, 5700K, 6500K
Note: $1/pc. The most efficient and expensive compared to A ,B, and C. Light quality slightly lower than B
