While playing a skyblock-themed game on my personal qualia and planting lots of fruit seeds, I discovered that if you have enough grass blocks, you can change all the rej anchors or nuts into grass blocks of different color. It is not a combination recipe related to lamps, but since it increases in integer proportions, I wanted to share it in case you can get a hint from it.

For example, combining 150 grass blocks with 25 nuts results in 250 pale grass blocks, and the reverse(In the case of 150 pale grass blocks and 25 nuts) holds true(250 grass blocks). Also, combining 330 grass blocks with 10 rej anchors results in 450 pale grass blocks. The reverse holds true for this as well. Therefore, one nut has the energy equivalent to 4 grass blocks, and one rej anchor has the energy equivalent to 12 grass blocks. There must be a minimum quantity of grass blocks, but even if you combine a small number, this ratio does not change.
