I actually don't use a basking bulb! Redfoot don't tend to bask and avoid really bright lights so I just have ches, I did Google incandescent bulbs when Mark said about them being banned and apparently they stopped selling them here in 2012 ? so I guess a reptile brand is the only way to get one, I get my ches on amazon so I would try there for the best prices, maybe look at chicken brooder bulbs? I'm not sure about that last bit?What basking bulb do you use? I have ordered the bulbs Mark has linked above but wondered if Arcadia do any? In future could get both from internet reptiles who I have used before
