I have converted my egg to led, some are flexible strips and some arerigid strips.
the link you post is a good price but be carefull, they are rated 6000k-8000k (this designation is for light
temperature, the higher, the whiter) so very very white light
. you are better off with 3000-3200k...wich is more like an incadescent bulb .
aalso choose smd5050 over other strips, they will give you the best results in my opinion.
i have two strips installed around the windows
to use refelection of the walls to illuminate the egg. it makes for very nice even light
the two following pics give you an idea...of course the camera make the light around the window look way to bright
this last pic you can see the whiter light that is set above the stove(its a 6000k rigid strip)..
