AMBR Modeling Bulb (Halogen)

This is the normal replacement bulb for the glowing modeling light in the center of the Lumedyne Modeling style Flashtubes. It is about 25 watts bright and does use your battery at a rate of one 200ws flash per 20 seconds of modeling light use. It is user replaceable by simply first removing the flashtube then pulling the burned out bulb straight out. After carefully replacing the AMBR into its legs, the flashtube fits around it and plugs back into place.
Manufacturer: Lumedyne, Inc.

The AMBR has always been the normal modeling bulb for any Lumedyne modeling style Head.  It has two small pins that fit into two small insulated legs that protrude from the center of the Lumedyne Flash Head's flashtube socket.  Use care when installing it to really slide the pins into the legs and not simply next to the leg in the sleeve.

Remember: If you were recently using the modeling bulb and are now exchanging it due to failure, it's going to be extremely hot.  Please use care.

Also remember for a longer bulb life be careful not to bang it, particularly when it is hot because that is when the filement inside is the most fragile.

The Modeling Bulb is about 25 watts and so it does drain the battery at about 2 amp hours.  It will drain a Medium sized NiCd Battery in about an hour if you just leave it on.  It is more intended to use for focusing assistance or checking if you will get reflections from glasses or background elements.  The modeling circuit does turn off during the recycling and then back on after each flash until you are done using it.

Don’t forget to turn it off and avoid wasting battery power when you don’t need it.  There are indicators on most heads to remind you when your modeling lamp is on. Avoid leaving it on during the day when you can hardly see it and it wouldn’t help with anything but will drain your battery. 

Hint: Some photographers just keep it out of the Head in their camera bag to avoid accidentally running the modeling lamp when they didn’t mean to and then only plug it in before an evening or indoor shoot. I want it there “just in case” so I just pay attention to the modeling light indicator on the Heads.

AFTE 800ws Flashtube for Modeling Flash Heads

AFTE Flashtubes fit all of the existing Lumedyne Flash Heads with or without the modeling light feature. They also fit in the new Extra Small Heads. They can be used at low power as well but should not be used above 800ws per Head as that is the upper rating of this flashtube's performance. The Flashtubes push/pull straight in/out and they will last for tens of thousands of flashes or one face down fall onto a hard surface. Any of the Heads can use this flashtube, however, the modeling lamp itself is separate and this flashtube does not convert a non-modeling Head to have that feature.

ARSG Black Snoot With Grid Set

The small ARSG Snoot fits over the Lumedyne flashtubes where the reflector normally mounts and tightens into place like any other reflector. It has a narrow opening for the light to escape at the open end. In addition to this limited field of view, the beam of light can be further limited and controlled with the small grid that fits the end of the snoot.

It charges Small Batteries as fast as 3 hours and can charge all sizes of Lumedyne Batteries and Cyclers. This is the "normal" charger for all batteries because we no longer offer a basic Trickle Charger. This is not recommended for batteries older than from 2002 with serial number below 149300. If your battery is that old, contact Lumedyne directly. If you paid to update your PEPI in the battery, then it is OK.
