If you can source the materials for considerably less than what most suppliers are offering right now then hell yeah. From my personal findings it seems you can save 10-30ish% depending on what you do and who you source from. sometimes especially if trying to replicate high dollar lights it can cost more to diy it. Cutter Electronics has been the best supplier I’ve found with a very user friendly website and awesome diy kits.

Im with merlin, i prefer strip/bar lights i would wait to see how Mars new FC series lights are they should drop mid August. Otherwise I prefer my 2 SP250s over my 1 SF4000 as the coverage is more uniform and consistent.
