Larger lamps that would fit into the large connector and have 2 times greater luminous capacity

Maybe you could craft the bulb into a larger lamp style block, similar to an Immersive Engineering powered lantern, to increase it's output. Also you could use dye to change it's style similar to the Fairy Lights mod.

Something I'd love to see is an electric lamp block that is a full block electric lamp. This would have the same luminance of a redstone lamp.

The other thing I'd love to see is fogged light bulbs by dying them. This would also make it easier to see if the lamp is on or not in bright areas since the texture would change on the exterior of the bulb.

That's a great idea!

Together with mods like Hardcore Torches, the need to electrify your Minecraft world with light bulbs really adds to the immersion. Please add bigger bulbs, and also more kinds of electric lights.
