The normal flourescent and incandescent don't put out any UVB.
The redfoot tortoise is from S. America - mainly on the rainforest floor and the grasslands. Hatchlings spend most of their time burried in the leaf litter (for protection and humidity) - so their UVB requirements are quite low. Some keepers keep them quite successfully without supplemental UVB, but I would err on the side of caution and use it. Lighting with good CRI, Kelvin and Lux will stimulate normal behavior and appetite - then the tort can be provided with D3 through diet.
