It is Cit Resource Pack, so no mod is required to get the items other than Optifine. This lamp can be functional and glow. You need to change the name of certain items to get the CIT items, then place those items on the item frame to get it. Compressed pack contain CIT Resource Pack and Catalogue Map.

How to Use CIT Item:
Convert some vanilla blocks or items into CIT items by changing their name using ANVIL. Items you'll need for this pack is "Glass Bottle" and "Stone". Example: Change name of "Stone" into "Stone_1" to get CIT item called "Stone_1". Place the item on the invisible item frame. To get invisible item frame type "/give @s item_frame{EntityTag:{Invisible:1b}}". you can also get it from chest on the catalogue map.

I was experimenting with making sphere on the Block Bench, and after couple attempt, I gave up. They somewhat look sphere in some angle, but not in other, so at the end, I was left with bunch of spheroid, and thought, although they are not that sphere, I could still make decent looking street lamp with it, so that's what I did!

Initially the concept was to change regular glowing vanilla block like sea lantern into CIT street lamp, by placing CIT(with the item frame) on the vanilla block by enveloping the block with CIT Item. However I quickly realized, when the item is to big, where the distance between the source (CIT Item on the Item Frame) is more than 3 ~ 4 blocks, the CIT Items tend to disappear from view, when they are observed from certain angle or position. So the lamp is divided in parts; divided into base, post, and lamp, and for some of the items, the Item frame is placed more centered, not at the end on the luminating lamp part of the lamp (this description will make more sense when you look at the image or see it on map). Anyway, because of that you will have to build the street lamp to get it out. I am sorry for the difficulties, but the detailed instruction on the build is shown on the map, so take a look at that if you are interested. Some of the lamp design requires barrier block. To get barrier block, type /give @p barrier. You can get barrier block only in creative mod. First five designs (Glass Bottle_1001 ~ 1005) requires barrier blocks and rest of them (1006 ~ 1010) don't necessary need barrier block, but you can still use it to make it look more clean.

On the map, you will see that it is organized into three sections. Each section shows: Item with glass block and visible item frame, glass block and item frame to show where certain items go, and lastly the items with barrier blocks and invisible item frames in place of the glass and item frames.

Hopefully you can incorporate the street lamps from this pack to make your perfect build!
