I like the aquatic and reptile tubes, you get such a variety of interesting colours , shame they’re quite expensive!

You could use the cover of the fixture to protect you from the UV radiation of this lamp.

@AH: Oh totally they are something to admire and guess what this only cost me £0.50 at the car boot sale! @dor123: Unfortunately this fixture doesn't have a cover as it is my blacklight fixture that I use to run any 15W tubes (except the UVC ones which I got like 2 years ago) I would need to grab a spare diffuser even if it is a different shape from the fixture
