I bought these from eledlighting.com:
Ultra High Lumen 4FT LED Tube T8/T12-Frosted-Cool White (5000K)

SKU 4UHLT8X020UN50F-P50 (50 pcs sku)
the color is 5000K and each tube puts out 3000 lumens.
They really light up my shop.
They also have 8ft single pin tubes that put out more light than a "HO" tube
