There are bigger ones that emit more light. But they are intended for use in darkness when your vision has night adapted (wait in the dark for a few minutes). You won’t see them glowing in room lighting, if that’s what you expected. If you want more brightness there are flashlights with locator LEDs. Those consume some battery power so you eventually have to recharge the light, but it is a nice feature. Come over to!flashlight@lemmy.world if you want suggestions.
