The Light Aircraft Pilots License (LAPL) differs from the full EASA Private Pilots License (PPL) in that it only requires 32 hours of flight training. It also does not require an EASA Class 2 Medical which means the medical is less stringent. These differences make the license more affordable but it does have its limitations.
The LAPL is a European license and therefore can only be flown in Europe (these rules are due to be relaxed soon). You are also unable to add extra qualifications such as a Night Rating so you are limited to good weather, by day. You are able to ‘upgrade’ to an EASA PPL at a later date.
