Questions & Answers

ARI F : What is the difference between these and monolights? AriPETER C : these are powered by a normal light socket and have no adjustable power. most monolights have adjustable power and have a separate ac power cordROBERT M : These are technically mono-lights. The main difference between these and a full size, full featured mono-light is that they have no modeling lights, no way to control power output and you need some kind of a lamp base to screw them into. There is also no way to plug in your camera or pc cord. These units are strictly slave units that will trigger when another nearby strobe fires. They're more suited as accent or background lights or to give some extra fillKEVIN C : These are not adjustable for power - also, only as powerful as a very low powered monolight. The DO work well inside light fixtures when you want to show lights in the lamps, and a few of them can be used to light a background. They are cheap for a reason - they only have so much power, and it is always the same amount. I actually have three of them, and like them for adding a bit when shooting houses.YOUSRY M : This is used to fill in background light if needed it has a sensor and if it senses that there is not enough light from camera it will go off when the camera flash is used
Shopper : What do you need to use this (I am new to the whole thing): would it work using any lamp and screwing it in or do you need a dedicated tripod/setup? Thanks!SAM A : It will work with any lamp but you must have a swivel socket to aim it at the subject.ANNETTE S : Just screw it into any lamp. Just make sure that the sensor can see your master flash or it will not go off.KENNETH E : This will work as a slave in any standard light or lamp socket. I use mine with clamp light fixtures as well as inside standard lamps to have them flash to appear that the lamps are on. I use 3 of them inside of a 7' x 7' hi-light box as well. These are not designed to be primary lighting but they are great to add light to smaller dark areas etc.DAVID M : This will fit normal light fixtures, but that will only help if you plan to bounce on a white ceiling. You will need some sort of fixture that articulates if you are going to use it in any other way. You should be able to find a clamp on fixture of some sort on adorama . com, or go with a simple light stand combo with a fixture for this style slave flash and a cheap umbrella.TIMOTHY E : Yes. I screwed mine into a standard desk lamp fixture, and it worked fine.KEVIN C : You can use a dedicated socket and stand (I use mine that way with umbrellas) or in a regular lamp. Even replace regular bulbs with these if you want. I trigger mine with a cowboy studio remote connected to either a flash or the "master" and the slaves flash when the others do. I find I have to keep my shutter speed under 180 - the flash will freeze the action but too quick and I have the shutter open and close before the strobes fully fire.CLAUDE S : Works with any standard light socket. You do not need a dedicated tripod.SKIP H : Just screw it into a standard socket and fire your camera flash to trigger it.
Valery K : How exactly is it controlled? PC connector?MIKE S : It is screwed into a light socket that is triggered by either the camera flash or alternate flash. No PC connector.EDWARD W : Some brands have a pc connector. Mostly, these are self contained slave units where if they have power they are in slave mode. Unless they specifically say it has a PC connector, I'd assume it is flash slave only..meaning if it sees a flash it flashes too.SAM A : No, it is triggered by the flash from your camera. No wires are neededCLAUDE S : It has a built- in sensor that is automatically triggered by the light of your camera's primary flash. There is no requirement for a physical connection.CHRIS C : Works as a slave. Has an internal sensor. We you fire another flash, this one will go off as well. I use it mainly as a background light.PETER C : no, by optical trigger. I only used it once as it goes full power and can't control it. I opened it up to connect jack so it could work by pc connector and it stopped working. Totally my fault but since i considered the unit unusable for me at least, it didn't matter. i mod a lot of my equipment so not sure why it didnt work but like i said i don't have use for something that only fires at 100%. i mean you can use neutral density fabric or just shoot at whatever camera setting you need and it works. just didnt work for my applicationTOM B : This is a Slave Flash, so it fires when another Flash goes off that it can see. Works good. Use a flash on your camera to trigger it.MARC M : it is triggered by the light of another flash...so you have to use either a built-in flash or hot shoe flash or wired flash as the primary and these are used for fill or highlight positions.TIMOTHY E : No connectors. It has a photocell that senses when another flash fires, and then flashes itself at the same time. It has to be used in conjunction with another flash. It only works well with a simple flash that flashes only once. A lot of on-camera flashes fire twice in quick succession, once to set light levels and a second time to actually take the picture. This flash will go off on the first flash, and isn't able to recharge in time for the second flash. This slave flash is only suitable if your master flash has a mode where it only fires once to take a picture.JEFF M : I fire this flash with my stobes in the studio. I use it as a hair light and it fires when my studio lights fire. It works great. I use filters over the top of it when I need to reduce the flash output.DOUGLAS C : The slave flash I have is not this model. I have a battery powered unit, but they work basically the same way. There is no connection to slave flashes. When they are turned on they are armed and then they are triggered by the flash of light from the on-camera flash (either the built-in flash or one mounted on the hot shoe). The only restriction is that they must be somewhere in front of the camera so they can sense the flash. This would, of course, preclude placing one behind the camera. Slave flashes are a very simple and easy way of adding an extra flash to light a scene.

VERY useful, but fails quickly

Sadly this failed extremely quickly (50 actuations), but the usefulness of this product is off the chart. Going to give it another chance though, as I love it otherwise!

Great for extra lighting

These strobes are great to fill in lighting situations. Although not adjustable, for the price thet are very handy to have on hand at a shoot.

You can't change the output however you should be able add some sort of translucent material in front of it to defuse the light.

Excellent VAlue

I ordered the AC socket (LTSKE) the Background Lite Stand (LTSB) and the Filter Set (LTACF) with the AC Slave (LTACS) and am very pleased with the set-up. I use the light for fill lighting or add filters to change background colors.

Big Flsah for Very littlt Cash.

This is one of my better additions to my bag of photography tools. The Flash unit adds to more options and lighting effects and creativity during shoots. Its small size allows placement in verious location that only add to to creative photography. It ma already be, but if there were a battery powered connection/power source, it would only increase its worth and allow unemcumbered (no wires)effects and lighting.

Exactly what i wanted to finish of my strobe equipment. i couldn't afford extra monolights and this did the trick to give me my 3 dimensional lighting.

Great for the price

Pretty great little lights for the price. I use 2-4 of these in a DYI softbox and considering that they've saved me hundreds of dollars I'd have otherwise had to spend on "real" studio lights, I like 'em a lot.That said, I've bought 5 of these and one of them only lasted about 91 days (I say "91" because they're only warranted for 90, and I was out of luck when one died).I wish the output was variable but hey, for less than [$], these are still a good deal. I add a layer or two of ND material to cut the light when necessary

Great studio flashes for the money

I purchased these mainly for use with our cub Scout pack. I have my backdrop setup with the American flag and as the boys earn their awards I photograph them and their leaders/parents. The lights are consistent and beat trying to photograph with the metal halide gym lights, or the harsh on camera flash. The lights shoot into 24" umbrellas which softens and evenly spreads the light. I really like them - no regrets.

Reliable & Affordable

I mainly use a couple of these with light stands and umbrella's when I do portraits on location. They are small and portable and I actually keep a spare with me just in case one should go out during a shoot since they are very affordable. I have good results and often use them in the 'slave' mode using my speedlight since it gives me more flexibility to handhold my camera during modeling shoots. Plus if you wanna use them for fill flash you can just screw them into any light socket.

A fun & sturdy flash

I started using these as a cheap way to learn studio lighting, but as I have moved on to more professional quality mono-lights, these little bad boys are always in my lighting kit. They are handy when you need extra light in any situation. The latest set is to replace ones that have worn out from use. They are not perfect, they do not work well outdoors, and the slow recycle time can lead to a few wasted shots if you are not patient. An audible indication would be nice but you'll just have to keep a sharp eye out the small LED indicator of a full charge. They are worth the money and will continue to replace them as they wear out.

Decent

They are pretty good for how cheap they are. Creates a flawless white background if positioned correctly. With my external flash in auto it misses it completely. But like previous reviews said you just have to put it in manual and it works great. Deff over powers my flash so I had to order another. But they are a great addition to my equipment and a good fix if you cant afford studio lights.

Great, simple flash but...

For the price, these are great little lights. I'm using them in a softbox I made and they provide nice light. Since they're not adjustable, I increase/decrease by either moving the lights closer/farther or by removing/adding layers of my diffusion material. Only problem I've had is getting them to sync. I use on-camera flash to fire them and I've found that I have to bounce this flash or the slaves don't sync. It's not a huge problem but it can be aggravating. Bottom line is that these are a great addition to my small studio.

Good, cheap background light solution

I have two of these slaves to light the background of my studio setup. Each is screwed into a worklight from Lowe's [$]. They work great with mini-barndoors or simply modify with a small piece of nylon cloth to soften the output. You can't beat them for the price!

Impressive

I'm impressed by the results I get with these low price lights. I bought 4 of them and use them in a 3 or 4 light setup for perfect white isolations but tried them for standard and lowkey portraits too. They never failed to trigger so far (2 weeks usage). I didn't have to do any work in photoshop to have pure white backgrounds.

Unexpected problem

When used with on-camera ETTL the pre-flash triggers the slave and totaly confuses the camera flash. I found it mandatory to switch the (Canon 580) flash to manual mode and then it worked fine.

Never misfired, not even once, and have been dropped more than a hot rock.

Although we are just starting out we have had noting but great success with this product. Bought 2 just to experiment and find they are a great accessory light for fill, hair, or background in portrait work. Never misfired, not even once, and have been dropped more than a hot rock. Great product and if you ever decide to stop making them please let us know because we'll stock up on them for sure.
