I can't get the node ( node-red-contrib-tsl2561) for this to install, it has lots of errors, Im trying to use the lux sensor and get a value returned, maybe another way to do it?

Show us the errors when you try to install it from the command line, go to your .node-red folder and run
`npm install node-red-contrib-....`
And copy/paste the full output here.

When you see errors with things like `error: ‘v8::Handle’ ` that often means it is an issue with the version of nodejs. I see that you are using 12.x and I also note that the node has not been updated for nearly 5 years. That almost certainly means that it is not compatible with version 12. Unfortunately there is no link to a github repository from the node's page so you cannot take the normal course of adding an issue there.
However the problem itself appears to be in the module used by the contrib node, which is [https://github.com/sonnens/node-tsl2561](https://github.com/sonnens/node-tsl2561). It has not been updated in 6 years though. You could try submitting an issue against that and see what happens. Otherwise, unless you can fix it yourself, I suspect you will have to find a different solution.
