Thanks Jasmine Ideally I need something to provide warmth but not light as I want to leave it on all the time at the moment. Buddy has been poorly and has been in a very small hospital cage which was easy to keep warm with a heat disc underneath etc, but he's recovered enough to find the hospital cage constricting , and his usual cage is too large to heat effectively with heat disc/fleecy blanket, so I thought a heat lamp might be the answer. I've been looking at the reptile infra red heat lamps which are widely available but I'm not sure if they'd be suitable or not?
It's best to find bird heat lamps that are bird friendly only mostly because some reptile lamps can be too hot for birds and also some may be covered in PTFE (polytetrafluoroethylene), the same polymer in nonstick cookware that can emit toxic fumes when overheated. I'm sorry my links couldn't be of use but maybe they'll come in use for another situation
