With Luke, very hard to tell from photos, but, lightsaber colour looks too dark. Photos below of real ones. Also, evidence of opened bubble to right top corner.
Also worth a look here as much better pictures available: https://www.imperialgunnery.com/lightsabers.htm
Ben - paint wear and broken sabre (can’t see tip in bubble) too suggests not a factory sealed bubble.
In picture - the sabre in the hand is real. Compared with the loose fake one - fake one is a bit bigger and rounder and tip is more solid (although tip comparison not an issue!)
Agree with Cazza regarding repros (although I keep the ones I’ve ended up with as a reference rogues gallery in a bag of shame). Given your figure budget posted in the other thread you could easily chip away at loose complete examples with real accessories well within the £100 per figure budget...
In short yes. Mine’s in a converted loft where I also often work, but, was forced downstairs by the last heatwave. This one wasn’t quite as bad.
I try to vent the room to allow cooling, but, balancing ventilation with not allowing direct sunlight in. So in summary a damned if you do damned if...
