I'll take those 330w retrofit CMH or color master 360 CDM bulbs that fit in regular old magnetic HPS and MH 400w ballasts any day over current LED tech or the newer digital square wave 315 ballasts/fixtures.
You can still find box loads of those retrofit bulbs on ebay for cheap. They still got the bigger 860w for 1000w ballasts too. Get em while you can before they're all gone forever! Analog CMH is king of the HIDs!
