1500 lumens for $69 isn't bad. The rigid 20" bar is 3200 lumens and about $500. Of course the floodinator is 40,000 lumens (400w) for less $$ than the light bar.
Lumens, Lux, candlepower, blah, blah. All marketing jargon.
As long as it is just to light the pit or bow,pick something affordable, use 2 of them, and if it isn't enough light add another. Truth is you don't need to be blinded in the cockpit.
Different story if you are looking to raise bait though.
