Gas Struts...150# each or total for both?

We ordered 2 (two) 150# gas struts using the info I gathered here on the forum. Totaling 300lbs!
But now that I have them in hand, I'm thinking I should have purchased 2 (two) 60-75lbs struts to equal somewhere around 150lbs total.
I have not installed them yet cause I'm not to sure.
Thanks
