Welcome To Terry's Forums calitrano,

Its all safe right??? That depends on who you ask.

In my case I am here in the kitchen where my cheap fixture is located.
I do not leave it on unattended.

Who really knows if the fixtures were safe before the mod.

They are UL listed but that means nothing, UL tested or approved may be better, not so sure, now a days.

As long as your foil is not to close to the ends of the tube then you should be fine.

Have a good day.
