These are 240v downlighter bulbs but I cannot find out why there are two types and what they are used for. I also cannot see any difference in the bulbs just looking at them.

Sorry Peter but they are the same price.

Mac is correct, the reason is that a GU10 lamp has an aluminium reflector which reduces heat to the rear. Whereas the GZ10 lets about 65% of the heat out to the rear (Cool beam) which will cause damage to a normal light fitting. Hence the chamfered back so that you can't fit the wrong type.

Krypton bulbs contain pure inert gas which allows the filaments to run at a higher temperature, emit a whiter light, and enables enhanced visibility for a given power consumption compared to Vacuum bulbs. Halogen bulbs contain a technically advanced mixture of active and inert gases. The active component re-cycles tungsten from the glass back onto the filament, enabling the use of a hotter, brighter filament. They are the ultimate filament bulbs producing the best combination of white light, visibility, and safety. The glass is thicker than krypton and vacuum bulbs, and is hardened to produce a mechanically stronger bulb.

Erm no, don't think you mean that, Krypton is a Noble gas (like Argon, Neon, even Helium) while Halogen bulbs as so called because they have Halogen gases like iodine or Bromine in them. Halogen lamps have tungsten filaments and can run at higher temperatures than Krypton filament bulbs making them slightly more efficient, but Krypton bulbs can also be gas-discharge (like the tubes in a strip-light) lamps where the gas itself causes the luminescence as it conducts a current.... very bright, very effective

in GU the U means universal so you can use these bulbs in a GU and a GZ fitting. The GZ bulbs can only be used in a GZ fitting.
If you look at the ceramic edges on the bulbs you will see the GZs are at right angles whereas the GUs are chamfered of at 45 degrees

about £5 a pop.
