The BMHM Battery provides 300 flashes at 200ws with a Four Year pro-rate warranty. It uses a double deck of NiMh battery cells and is about 2.2 inches tall and weighs less than three pounds.
This is the high power 2400ws Basic Head and is a great value. It has high quality circuits and uses the same flashtubes as the bigger Heads but in a smaller molded enclosure so they are also less expensive. They are electronically the same as the larger heads except for the lack of the household sync jack.
It is true that the "Basic" Extra Small Heads are the only Heads currently offered without a modeling light which is one of the reasons that it is less expensive than all the rest of the Lumedyne Heads. It also saves money by avoiding duplicating the Power Pack's ready indicator on the Head. This is the best value for a Flash Head that just flashes, and does it well.
This Head includes a grid and diffusor set with the reflector and 2400ws Quartz non-modeling Flashtube (AFSQ).
This Power Base will power an Extra Fast recycling Lumedyne system from any AC wall outlet worldwide. It has an interchangeable AC power cord and you select that at purchase, but the default is the American cable as the XACU.
This AC Power Base also charges a NiCd or NiMh Battery with a Hyper Speed Battery Charger built inside of it with a short DC charge cable that can be mostly hidden inside the body of the power supply when not in use.
The Basic Signature Head is very strong with the square metal shell but it's still only about one pound. It's sold separately from the Head Cables to allow you to select from 5 to 20 foot options. It works with any Lumedyne Head Cable or Head Extension Cable.
The Head originally does include the reflector, 2 diffusors, a metal snoot and the 800ws Flashtube and a 25 watt modeling bulb.

The BMHL Large Battery provides 450 flashes at 200ws with a Four Year pro-rate warranty. It uses three decks of high amp hour NiMh battery cells and is about 3 inches tall and weighs just over four pounds.
The X4BC goes between the Battery and most Lumedyne Power Packs to add 400ws of additional power to the Pack above it. It has a switch that controls: no boost, or add 200ws, or add the full 400ws to the Power Pack above it.
It is only about three inches tall and weighs about 2.5 lbs. and it will add an f-stop to the 400ws Packs since it doubles the available power. For the 200ws Pack, that's a stop and a half brighter. These are also stackable to go up as high as 2400ws by adding five of these to a 400ws Pack.
