[Optional] I travel extensively and love this new case. Evidently there was a previous case with the same model number that was a terrible case. This case is excellent. Padding is generous and the storage is well organized. The overall construction of the case is very good. I especially like the wheels and retractable handle.

[Optional] I bought these to keep in the Lite Panels travel case, they fit perfect but there is one problem.. the baby pin on the top is crazy loose, actually falls out! I contacted Lite Panels and the are redesigning them and said they will replace mine for free.

[Round] First of all you can use Sony NPF batteries to power this light. You need a NPF battery plate with 12vdc out. It runs about 3 hours in full power. Rechargeable AA batteries also work great but half the light power (runs about an hour and 20min). It is a perfect size and weight fresnel light. You can shape the light with barn doors if it is used at 50 to 75 degree. It doesn’t get hot so you can run it all day.

[Optional] Super deal! Big semi-hard zip-open case with padded dividers, good wheels, okay handle. Wouldn't put it on a plane as luggage, but it's light weight and terrific for rolling light gear around out of studio.

[Black] I ordered this to store a Dazzne LED lighting kit with three panels about 14x10 each. The panels all fit comfortably in the side slots, and the pocket down the center can hold collapsed spreader stands. Then there's room to spare for power cables, batteries, and other lighting miscellanea. The case seems to do a good job balancing compactness with sturdiness.

[5/8" Stud] This is the second case I own and use and they are great and quite robust.

[Aluminum] Took a gamble, works for Hard 1x1 geminis - 3 snug with dome diffuser. Or, 2 Gemini Hard 1x1 with more accessories. They insert laying on side w/o tightening knob.

[2.8 lb] Love this little light! Fresnel lens, spot or flood, just wish it was bicolor so I don't have to worry about gels and filters.

[5/8" Stud] Portable , powerful and extremely portable. Great piece of interview equipment , love the size. Had to add a couple of light stands. I use the lights most of the time on the AA batteries, makes it easy and convenient .

[4] This fit my 4 GVM 520 panels, stands, and lots of accessories. Seems well made. Would have liked to be able to lock handle in place, but not a big issue. Got on sale for $129 and was a great value and seems to be the only bag I found that was made for my equipment. Would definitely recommend at least up to $150.
