Pitch accent and devoicing of 点ける in the te form

So in the te form (点けて / TSUkete) it should be atamadaka, right? But the first mora つ is devoiced so does that affect anything? I’ve read somewhere a while ago that devoicing can cause the pitch to shift to compensate or something like that? In this case does the fact the つ is both high and devoiced affect the second mora け? Or am I totally hallucinating?
