Although given a slight mention to date, the issue of using lights for long periods of time may actually cause damage to your electrical system.
Every aircraft is designed with the use of electrical items like lights designated for various periods of time and perhaps in conjunction with (or not with) other electrical services.
During the design stage of all aircraft an electrical load analysis is conducted in order to ascertain if any limits need be placed on the use of various electrical services.
The use of lights in many light aircraft was possibly not considered or perhaps designed to be used continuously. This does not apply in transport category aircraft that have been using lights on climb and descent and on two-way air routes for many years and of course they have more electrical grunt!
I would suggest that many operators and pilots although supporting the use of lights (by day) for long periods of time have little knowledge if this is or is not likely to cause temporary or long term damage to their aircrafts electrical system.
In the light (!) of this, it would be wise to check if there are any limits on the use of lights and even wiser to discuss these issues including the load analysis data with your engineer. Globes are not the issue.
In the meantime I would be cautious in the long term use of landing lights.
