I agree with Faerybee.
If what you have is the compact screw-in bulb that has an electronic ballast included within the unit, then you can 'theoretically' use any normal light fixing in which it fits.
However, the light needs to be directly above the birds, not coming in from a side angle and the main advantage of using an avian lamp holder is that they are designed in a way to reflect the light down into the cage.
For that reason, I would recommend that you use an associated avian lamp (whether clamp on or standard pole type). If the light isn't being reflected properly, then the benefit is lost.
You also need to take care that you position the lamp at the correct distance and I strongly recommend that you use the light together with a timer to prevent accidental over exposure.
Real outdoor sun exposure is much superior to any avian lamp, so when the weather becomes suitable and you're able, choose outdoors over the lamp.

I can't quite visualise what you mean by this. Hopefully, it's something to place above the cage, that can be placed at the correct height from the top perch and the light can be reflected downwards.
