Question about Samira's heat

[The Night King]

I did purchase the luttron dimmer switch. I looked at letsmart and only saw a 50w and 100w CHE - the 100w was $35 - yikes

A quick google search showed this 75w (per wattage recommendation above) but it doesn't say "reptile" does that matter? Shows in the home & garden section.

Here is another that does say for reptiles but it's black infrared- not sure if that matters:

if not is there another you guys recommend?

thanks in advance-
