I say keep the lights where they are. I would watch your watering ... It should be every 2-3 days right now...and maybe just straight water and wait on the the nutes for a few weeks.
I just picked a few up today @ $14.97 and was 2700K so perfect for my flowering light I need. They also had( made by TCP)a 27watt 5500K for $7.97, I picked a few of those also. All worked perfect in my set up so no "special" light socket needed.
Looks awesome, nice idea on the cage grow! Those jalapenos look ready to pick. Don't forget to fry up some of those green tomatoes. As it gets hotter those tomatoes will get real thirsty.
