It takes 3 weeks to a month for arrival, but it comes at 1/10th the cost. i also know several folks who use 50w LED flood lights. i made the mistake of building my cabinet way too small and short. once the weather turns warm enough to get in the garage, i'll be constructing a taller cabinet/shelving to make it through the winter. i also severely underestimated the growth of figs. i can send you more info if you are interested in building, but i do think the 50w floods are the best option- you dont have to be concerned with heat dissipation- i just discovered them too late.
here is an example of a 50w for $20 USD and free shipping. you may find it less expensive from China, this one is located in Ohio.

At least this is a good problem to have, right?
