No, though they are all conducted without electric lighting, only candle light as are all the evening devotions during Great Lent.
Here is a link to an explanation of the Bridegroom services:

Neither snow nor rain nor gloom of night, tradition claims, will keep letter carriers from completing their rounds. To complete his mission of redemption and salvation, Jesus had to contend with much worse than that. Darkness, denial, ignorance, betrayal, cowardice, and the demonic all confronted Jesus as the Last Supper, on the eve of his passion. Yet Jesus pressed on, in spite of it all, demonstrating that his love for us, and his desire to save us, will never fail.
Jesus love is resolute. He would never force himself upon us, but he doesnt keep a polite distance either. Instead, he keeps knocking at the door of our hearts. Sometimes we open our hearts to him on our own, and welcome him in. At other times, we need his help. Maybe our hearts are frozen, and Jesus needs to melt them; it could be that our hearts are broke, and Jesus needs to mend them; perhaps our hearts are made of stone, and they need replacing with Jesus own, sacred heart.
Regardless of the state of our heart, Jesus persists in his efforts to open its door, not to assert his power, but to share his love. Nothing will stop him! Not even death itself.
