Help me upgrade the VISM VAFLFSP

Hello CPF's!First time poster here. I thought I'd post this here since I don't know of another place more qualified to answer. As you know NCStar/VISM is a junk tier importer of airsoft accessories marketed towards uninformed buyers. With that out of the way, they have a product with a great form factor that I toyed with and am sold on. That product is the VISM VAFLFSP, a A2 front sight with integrated flashlight. The controls are actually great and it's a great lightweight way to co-witness with a red dot sight on a rifle. The problem is that the advertised "150 Lumens Peak Output" looks like an old incandescent AA MagLite and looks to be more like 80 lumens to my amateur eyes. Is there an easy way to upgrade the emitters in these cheap lights to something brighter and more durable. There's nothing else exactly like it at any other price from my research:https://www.ncstar.com/optics-acc/flashlights/flashlights/vaflfsp-flshltar-front-sight200l-ledThanks in advance!
