[4] Awesome battery pack. I use it on location and it works perfectly with my 202VF heads. The fans are disabled when using with the pack. The only drawback is the weight if you have an assistant holding it while shooting.

[1000 Ws] I'm in the process of outfitting our studio affordably with some longevity in mind. You really can't beat this setup from speedotron. With two packs and four heads we have more than enough power to do product shots of anything upwards of 10 feet tall. We can overpower most of the ambient light in the room and with a set of speed rings from B&H we can hook up softboxes and other light modifiers. I hooked up with a basic set of pocket wizards and this seems to really be the ticket in out tiny 20x30ft studio.

[12.05 lb] Adding in some newer packs to supplement my equipment. Speedotron works well, is reliable, doesn't cost an arm and a leg, and don't need repairs too often.

[12.05 lb] Switching from Paul Buff's Ultras, I found Speedotron to be a very well built product. I get consistent light output to 1/10 of a stop at a color temp of 5500K, which makes for very easy photo editing. The bright 250 watt modeling lamp could be used for hot light photography if needed. I like the design of these lights with the fan to keep the unit cool, the twist handle to aim and lock, and the heavy duty detachable cord for compact travel. Truly a professional product. I am using one 202 VFCC in an Octodome for a main light and one in a soft box for fill. I get a very nice soft blend of quality light for my portraits. Power from the 2403 CX LV pack.

[12.05 lb] We use this for lighting product and portrait photography. Creates a lot of light with good tones and consistent results. Would recommend purchasing another head and more soft boxes. Reset is very quick and can shoot all day with them. Built in fans work great. Speedotron builds solid products.

[12.05 lb] Just used it in an airport shoot. No trip hazard so battery power was needed. Ive had Blackline traditional HEAVY power pack for awhile (2401A). To be honest it was gathering dust since I've moved to Canon 600ez-rt speedlights. The need for real power lights are less and less in this clean-high-iso-camera era that doesn't need the nuclear blast of a 45 lbs of 80's American engineering encased in heavy steel. But when you do need some portable powerhorses there are the newer kids in the block like Profoto, Hensel.... I was about to starve and give up drinking for few months so I can afford these hipster Euro units but this Digital Explorer came to rescue. Since I've had some black line heads I bought this wonderful workhorse. I was impressed with this unit. the consistency of output, the sturdy workmanship, the well thoughout case. The power is enough to go through big softboxes, 7 ft umbrellas or the like. The bad: You can only do 1:1 ratio or 1:2 ratio. The variable knob adjusts both lights at the same time. you can't adjust them separately . Black line users are used to this but the lack of other ratio makes it less flexible. But honestly, I think most will use to this to power just one head with a modifier. So its not that bad. The other bad. The menu system is horrible. its like trying to program your 90's VCR. But once you get used to it, it only takes a few minutes to check the battery level... sheesh. Its powerful, the flash duration is pretty fast (on 103's) battery life is not too bad and best of all you don't need to starve or give up drinking to buy one of these things!

[4] After 25 years, we've replaced our existing Speedotron with the 4803CX -4800 Watt/Second Power Supply. Works like a charm. No longer have to worry about arching with a toggle switch either.

[1000 Ws] I have been shooting with Speedo for years. Used lots of other packs too but always circle back to Speedo. Reliable and affordable.

[1000 Ws] This is the fourth 202VFCC head that I buy from Seedotron for it's reliability and strong construction.The first black line head I bought 19 years ago and never gave me a problem.

[4] This 1005 power supply replaces my 805 Speedotron unit and the improvements are great. The 1005 has a recycle beep tone (which can be switched off) which I always missed on the 805. Fast/Slow recycle rate switching means no more blowing fuses at locations with weak electrical wiring. The 1/4 sync outlet now works flawlessly with my Pocket Wizard Plus III's with no misfires. Unit is compact and weighs less than 8 lbs.
