Luci Pro Outdoor 2.0 has a clear finish, bright-white LED's, and will provide 150 lumens for incredible visibility outdoors or indoors.
Luci Pro Lux has a matte finish, for a warm frosted decor light, warm LED's, and provides up to 135 lumens.
Many of our biggest fans prefer to use the Luci Pro Outdoor 2.0 for an overhead light, providing enough light for many tasks. Those same people also use Luci Pro Lux as a table-top light as it is softer on the eyes with the soft-white LED's and matte finish.
Other than these differences, the main specs are identical. They both have a single USB port for two-way charging (with included 2-way USB cord), the 2,000 mAh battery recharges fully in 14 hours of direct (outside) sunlight or 2-3 hours via USB, last up to 50 hours (on low mode), and have a convenient top strap and adjustable base strap.
