Good idea and I did consider it, but they are about $5.50 each or $11 per set.
Instead, I went with some 7.5K 50W Ohmite from Allied on sale for only $4.68
I'll add a 20K 10W resistor in parallel to reduce the value.
Since I need six of these the price difference really adds up.
P.S. I agree about the power rating because it really doesn't really get all that hot.
