Further down you can read the translations of the texts of the crypts made by Egyptologist Wolfgang Waitkus. Based on these texts authors Krassa/Habeck come to the conclusion:
"Surprisingly the texts of Dendera contain actually essentially technical data and paragraphs, which can be linked problem-free with our "electrical hypothesis". Not only this: They represent an ideal, meaningful supplement and support our interpretation in an amazing way."
Author Habeck goes even further in claiming that Egyptologists are completely useless for deciphering the reliefs, since because of a lack of technical training they could not recognise a light bulb when standing right before one!! Literally:
"An egyptologist may be a specialist in his area, but is he able do detect electrotechnical knowledge in old texts and pictures? Hardly. He would probably never comt to the thought, because school book science anyhow categorically excludes this possibility."
But judge for yourself:
Bandeau de la frise:
Resomtus is alive with gloss in the sky (and) lives at the day of the New Year celebration. He lights up in its house in the night of the child in his nest, by donating the light to the country from the birth bricks. The sky is jubilant, the earth is pleased and the God chapels is glad, when he appears in his chamber in his procession barge at his beautiful celebration of the New Year.
The God with his disk has come to see him. Nehebkau gives him reputation, and the goddess with her disk, with godly body, rejuvenates him in his sanctuary.

As the text proves, there is no question about the contents of the reliefs. The texts describe the pictures as representations of statues, which were kept in these rooms. They give detailed descriptions of their extents and even the used material. A bulb made from gold - well, much light would not shine through it :-)
Even if one does not understand the contents of the texts, which admittedly sound rather confusing without previous knowledge, one should perhaps believe this time the egyptologists or at least accept the mention of the New Year celebrations as main theme.
Clearly visible is the fact that there is not the smallest suggestion which could justify an interpretation as light bulb in the texts. The function of these rooms was to keep the cult statues which were necessary for the celebrations mentioned. Further references to these absolutely clear circumstances supply the other walls of the rooms, whose texts are not shown here. As found so often, the whole theory is based on the complete neglect of all results of scientific archaeologic work. The light bulb thesis is pure fantasy without empirical core, based solely on the "looks like - was then"-method and takes no consideration of any facts - even not to those written in large "letters" right beside it.
