While the sun in the late evening is not as strong as late morning or midday sun it is still much stronger then the average uvb producing bulb. Any extra time out in the sun for a beardie is beneficial to them. Even 15 minute sun soaks will do them some good
The sun is very deceiving though, and you must be careful. one day I brought a few different bins/cages out just to test the temps and it was up there 130 degrees in a matter of minutes in a Rubbermaid bin on a 80 degree day. Just make sure your putting them out in a screen cage or something with lots of air flow (also screen keeps out bugs. FIREFLIES KILL BEARDIES DEAD), and nothing glass or clear/or dark in color like a Rubbermaid bin, as they can really cook in these. Take the cage or whatever your planning to put him out in and test it on a hot day, and check the temps throughout the day. Also giving a shade spot out in the sun is a MUST, so make sure your providing shade too. Other then the precautions we must take bringing them out, it is extremely good for them. That's if they like going out. I have some that hate going out.. They freak when they see a shadow LOL
