help with light change options

[cbrine]

Hey,

So I am new to the nano world. Have a 55gal with MH/T5 and LOVE IT! Would love to get the hood of my 24g nano cube retro with T5 bulbs. Anyone know best way, or where to get retro kit? looked into LED retro and was shocked it was so $$ (even the DIY kits). Really prefer to keep the hood on and just remove the PC lights.
Anyone offer any help? would be much appreciated!

thanks
