Lights for ZT48 HD

I bought a new Gravely 48HD mower about a month ago. I use it to maintain my mom's property. Depending on my schedule & the weather, I sometimes have to do it after work and its a 2-3 hour job.
I want to add work lights to it, and I am debating on the oem lights vs. led. I like the led because of the reduced power draw, but don't want any issues.
Any one have any experience with either route?
Thanks,
Rob
