Get this: we spend hours of blood sweat and tears creating 3D lightbulb backgrounds, and then some bright sparks start asking for 2 dimensional lightbulb backgrounds! Some folk are never satisfied. Anyway, ask and ye shall receive, and here are some more free lightbulb PowerPoint backgrounds.
There are a variety of luscious colours with gradients on these backgrounds. Some are quite dark though, and will require that you use some light coloured text. We knew you knew that, we just like patronising you.
As usual, each of the thumbnail images above represents a different background and clicking on one will open it up – already inserted into PowerPoint – as a template. From there, you can do what you will; amend it how you see fit and use it (or them) in your upcoming presentations.
