The lamp of you experiment is mostly fixed by the maximum intensity required as well as the wavelenght region you want to explore. Depending of your expecific experiment you can use one of the lamps you mentioned or the binary combinations (such as HgXe). You may wish to specify you experiment in order to check pro and cons.
I would advise you to think about LED

Dear Dr. Fernandez-Garcia, thanks for your valuable answer. I am interested to know which of these lamp is best suited for the photocatalytic decomposition of water either by UV light or by Visible light.
Dear Bikash,
The light driven water oxidation/reduction is one of the main project in our group. Recently I gave an oral presentation on an international meeting. Several slides from my presentation are enclosed.
Thanks Dr. Zhi Jiang . Can you please explain which of the lamp is best suited for visible light assisted photocatalysis.
Agree with Prof. Yurii and Zhi mostly Prof. Yurii. You should try by using LEDs. It is good.
White light source Xenon lamp has uniform excitation intensities across all the visible range.It,s intensity decays over time, but the bulbs have a longer lifetime. Light emitted by this lamp can cause skin and eye damage.
Can anyone share the link or the reference which have a detail discussion about the different lamps and LEDs used and the wavelength range they cover ?
Please have a look at the below link.
