Make an electrical light emit sunlight - possible?

[njugul]

Doubt it's possible since sun exposure of a block seems to be a function of direct connection to either the sky above the block or a connected block, but maybe someone knows more?

 

Plants need light from "sun" >= 8 otherwise you cannot plant them.

Using normal electric lights will emit a "blk" light of 7.5. You can mod this to also give 15 or more (max for sun) but planting seeds does not care about this light.

 

So is it somehow possible to make electric light emit the correct light?

 

I could still mod all seeds to need no light of course, I know.
