I've been trying to make an LED light similar to the one showed above, but I can't find a way to make the glass material be simultaneously transparent and emissive like in the picture. I tried making the glass itself emit light, but it looks really dull compared to the picture. I also tried making the top and bottom faces of a cube emit light, but that doesn't light up the glass in between. (Picture is in rendered view below).
The glass texture is just a principiled BSDF with full transparency, yellowish base color, and everything else set to 0, and the lit up planes are just yellow emissions of strength 10 with a gradient texture.
