Cfl type bulbs, the ones that screw in, sometimes burn reptile eyes and are not effective UV sources. They should not be used over tortoises.

Most of the care info out in the world, especially from pet shops is all wrong, and they sell you all the wrong stuff too.

There are four elements to heating and lighting:
  1. Basking bulb. I use 65 watt incandescent floods from the hardware store. Some people will need bigger, or smaller wattage bulbs. Let your thermometer be your guide. I run them on a timer for about 12 hours and adjust the height to get the correct basking temp under them. I also like to use a flat rock of some sort directly under the bulb. You need to check the temp with a thermometer directly under the bulb and get it to around 95-100F (36-37C).
  2. Ambient heat maintenance. I use ceramic heating elements or radiant heat panels set on thermostats to maintain ambient above 80 degrees day and night for tropical species. In most cases you'd only need day heat for a temperate species like Testudo or DT, as long as your house stays above 60F (15-16C) at night.
  3. Ambient light. I use LEDs for this purpose. Something in the 5000-6500K color range will look the best. Most bulbs at the store are in the 2500K range and they look yellowish. Strip or screw-in LED bulb types are both fine.
  4. UV. If you can get your tortoise outside for an hour 2 or 3 times a week, you won't need indoor UV. In colder climates, get one of the newer HO type fluorescent tubes. Which type will depend on mounting height. 5.0 bulbs make almost no UV. I like the 12% HO bulbs from Arcadia. You need a meter to check this: https://www.solarmeter.com/model65.html A good UV bulb only needs to run for 2-3 hours mid day. You need the basking bulb and the ambient lighting to be on at least 12 hours a day.
Here is the current and correct care info:

Thank you for all the details. What is the difference between ambient, uv ave basking. I understand he hearing my home gets 50 F at night where should I keep the temp to for a baby hermann’s

All of that is explained in the linked care sheet. Read through it a couple of times and most of your questions will be answered there.
