[1x E26/E27] I use these small strobes in the studio to provide some fill and accent lighting. In the past year I have purchased 7 of these and everyone has performed as expected.

[1x E26/E27] I use these for table-top product and still life and in a tight home studio space. I use them with Impact porcelain sockets and 12 reflectors though obviously these fit in any standard light socket. They provide adequate light for my purpose and recycle quickly enough. Each bulb is packed with a sync cord. The bulbs can be triggered either by another flash or with a sync cord connected to one of the bulbs. To the person who mentioned that the sync plug on the bulb is too deep in their reflector's neck and therefore the cord doesn't have enough room to plug into the bulb, consider the Impact socket and reflector combo that I mention above as replacements; these are inexpensive and will allow the miniplug enough room.

[1x E26/E27] You can't beat the price - and with multi socket adapters, you can combine several make seriously powerful light setups for next to nothing. You just connect the sync cable to one and the rest will be triggered automatically.

Some complain about not being able to plug the included pc sync cable once you screw in the bulb due to the admittedly short sighted idea to place the port in the back, but this is easily overcome by buying a 3 dollar socket extender from Home Depot that easily provides enough clearance.

I would discourage others from buying Impact's porcelain socket with stand/umbrella adapter as a match for this because due to poor design the metal sleeve inside the socket breaks easily. Use a different product/lamp. Nothing to do with these flashes-they are awesome!9

[500 W] Like the idea of rectangle 110 degree or so unlike 180 degree, it's give me a better control. extremely fast re-charge.

[120 VAC, 60 Hz] Great bang for your buck! My only issue is the placement of the test trigger, its right on the back near the threads so its a tight fit when i screw it in to my power source.

[1x E26/E27] I HAVE ONLY USED THEM ONE TIME, BUT THEY HAVE GREAT LIGHT OUTPUT, I HAD TO USE ND FILTER TO TONE THEM DOWN. I DONT THINK YOU CAN GO WRONG WITH THESE LIGHTS, GREAT FOR THE PRICE.

[10' / 3 m ] I'm a studio portrait photographer and have used this as a hair light for over 20 years. Can't be beat!

[Yes] I use it as the slave, but because I cannot insert a synch cord once I've screwed the light into the socket, I can only use these bulbs as slaves. I can adjust the output by using a set of old barn door I had. Very fast recycle time.

[Yes] I ride a motorcycle and because of that, space is an issue. Using a light tripod as a lightstand, a clip light and this I was able to bring a portable studio in my saddle bag.

[500 W] Bought a new pair of these lights for use in our passport photo room - after 15+ years, we thought our old ones had finally petered out. Turns out it wasn't the lights - they still work perfectly - it was one of the wall-sockets that had to be replaced. At least now we have a backup set!
