Questions & Answers

Shopper : Is there a way to prevent this slave from firing by flash? I purchased a wireless slave trigger to use with the unit, however it still fires when it senses another flash despite having a receiver plugged in. I need to figure this out ASAP as I was intending to use these lights at a wedding in a few weeks, but they won't work if every other camera flash will set them off!DONALD B : Try covering the sensor. Haven't used mine in a while, but remember it being on the unit under the cover.CYNTHIA S : No, there is not.MARTIN K : There's no built-in means of disabling the sensor, but you could simply cover the sensor with tape.MARTIN K : There's no built-in means of disabling the sensor, but you could simply cover the sensor with tape.CHRIS N : I haven't tried this, but there is a little sensor if you unscrew the cap. Try covering it with black electrical tape.GEORGE M : I use my Adorama AC Master Slave with colored filters for accent lighting in my home studio. I do not use the flash to do weddings. Use a good On Camera Flash. Use your slaves after the wedding ceremony to take special photos of the wedding party and ask the guests not to use their camera(s)till you take the photo you are after.OTHERWORLD D : Unscrew the plastic lens cap and cover the sensor with tape? There are three little things in there. Not sure which one it is, but as long as it can't see light, it should only fire when it receives a pulse. Having said that, I was under the impression the sync jack would over ride the sensor.ANTHONY V : Not really. That is how these flashes are designed. You could try to put black tape over the slave sensor which should block other flashes. However these are not great for weddings. The recycle is SLOW so if shooting fast not great option. AARON W : I don't think there is a way to prevent this slave from firing when it senses another flash. It is just a cheep slave flash so don't expect that much from it! It is great for low-importance photographic needs, but don't rely on it for serious work like a one chance wedding !!!. Spend the money to purchase a slave flash that can be wired to gour camera or a pocket flash system to ensure proper flash function at the important wedding.C EDWARD E : I had the same issue. I wound up unscrewing the clear lens, the taping a small piece of aluminum foil over the trigger (the sensor that is not the LED light). I had to use aluminum foil to make sure all the light was blocked--tape alone wasn't 100% reliable. Hope this helps.
TERESA B : Can this be used with a softbox and if so, what type of adapter is needed?ROBERT T : I own a few softwares, and the few that would probably work are designed for large compact fluorescent bulbs. My Chimeras take speed rings for all kinds of strobe heads but this one fits in a Standard light bulb socket. Adorama used to sell a light bulb socketted bracket that would fit on a lighting pole and hold a studio umbrella. Shooting through an umbrella can be a very effective way to get a diffused lighting source so you might thing of taking this route. Note that these units have no modeling lights - it's just a flash. I used them for shooting tricky home interiors where I could through them in an existing lamp or ceiling fixture. Since they aren't shaped like normal bulbs they won't hold a traditional lampshade or fit into tight lamp housings. Most of these were marketed under the label Morris, but the ones I bought from Adorama are essentially the same. Note that the reflectors around the flash tube are metalized plastic and there is no venting for internal heat buildup. This means that if you fire them several times without a break the reflectors will melt. So be easy on them. That said they are handy useful items ANNETTE S : A soft box that is made for continous light with a regular screw-in base will work. You could also shoot through a sheet or shower curtain that hangs in front of your master. Caution should be used if you are using this as a slave, because the light from another flash will not necessarily be strong enough to trigger the sensor through the material.JOE M : I use mine in a brolly box all the time...I just use an umbrella holder with a ac base...the unit fires great. It recycles a bit slow...but works great.MICHAEL R : Yes, it certainly can be used with a softbox and no "adapter" should be needed depending on how the softbox attaches to the light head. Keep in mind however that his is not a very powerful little unit and putting it in a softbox will make it less powerful still. I generally use small units like this as "kicker" lights in male portraiture and "catchlights" in the eyes.LEE B : The unit screws into a standard light bulb socket so if that's what's in your soft box the answer is yes. Just make sure if using as a slave unit (no pc cord hookup) the sensor is positioned to pick up the flash from the master unit. FIDEL M : Do you mean power adapter if so you don't need one they come with a power socket and if you mean adapter to fit a soft box I'm pretty sure you don't need one they would just be put like any other flash I use mine with umbrellasCHRISTOPHER S : You can use this with a soft box, you would need a speed ring with 4 thumb screws that tighten around the Master Slave housing. I would recommend a small soft box as weight may be an issue possibly breaking the Master Slave and the soft box coming off.
Roseann E : doe this come with a sync cord like the smith vector bulbs?JOHN W : Comes with a 1/8" to 1/8" cord. Not very long, though.JORGE C : That´s right, it comes sub mini to pc. Hope this helps.C EDWARD E : Yes. Mine came with a standard sync connector to sub-mini plug, which is plugged into the flash itself.MITCHELL C : Ths slave does come eith a sync cord which works fine. This is a good unit for the price. Thanks Mitchell CaylorRAFAEL C : noJAMES A : yes, comes with the sync cord although you may have to get an extension. Any mini ac stereo plug for audio or stereo use will workOleg P : It does come with sync cord, don't know if it's "like the smith vector bulbs" though.LAYTON E : Yes it comes with the sync cord

FLASH UNITS ARE PRICED RIGHT

FLASH UNITS ARE PRICED RIGHT. HOWERVER I'M NOT HAVING ANY LUCK WITH UNITS SYNCHRONIZING WITH BUILD IN FLASH OF NIKON D90. MY INTEND WAS TO USE ONE FOR A FILL IN LIGHT AND SECOUND FOR THE BACKGROUND . I DO NOT KNOW WHAT TO DO TO CORRECT THIS.READING NIKON USER MANUAL DOES NOT HELP ME. NIKON HAS ALL KINDS OF FLASH UNITS AND THEY ARE TRYINGTO SELL THEIR PRODUCT.

Used like stobes, very nice results

I have six of these on a total of two light stands and use them like stobes and fire them with pc cord. Works great, looks like I used expensive stobes. Buy stobes if you have the money, but if this is a hobby and money is a factor, these will do the trick. Not for rapid shots, but they work for a shot every ten sec's. So far I have great results with all Adorama named products, I hope they keep putting out great priced, quality items for the money challenged. They only have one light output, so you will have to figure your settings manually, so be prepared to take it off the green square.

Studio Flash

I use these in a dual light setup (umbrella reflectors) with continuous output 5300K lights. They give the extra "pop" that portraits need and even out shadows. I've seen similar strobes for 4X the price but these do the job just fine. When used as a slave the sensor is sensitive enough even if the master unit is a good distance away.

Perfect for that extra bit of light

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.

Great for the price

I am a serious DIYer and use these for everything. They are versatile since there are so many varieties of light sockets available for custom made lighting. I group these together if I need more output such as a main light. I also started modifying them slightly to include a push button on/off for the optical slave (see photo) which makes reconfiguring them much easier and no need to discharge them if they are charged and you don't want them firing on the next shot. It would be nice if this feature was built-in, but it's really simple to DIY.

Not what is shown online

All the technical details aside, the product is shown as black and I received the bulbs in white. I did not get what I was expecting. Yes, they work. I have not had a chance to use them properly yet[...]

Excellent Value

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

Great Light for Bargain Price

A great light with strong, consistent output for a bargain price. I bought this for use as a backlight, and it works very well in that capacity. The small size makes it easier to hide behind a subject. It is a bit trickier to modify, and I wish it had a variable output, but I knew it didn't going in--for that price I certainly didn't expect it. With a little DIY ingenuity, it's no problem.

Very nice light for cheap

I've been using these for product shots and portraits of the kids. They have strong output, and because they screw into A/C sockets you can do some interesting things (like taking a picture of a room with these in lamp sockets for a cool natural effect. They only have one level of output, but that's easily modified with umbrellas, socks, snoots etc. They are an excellent low cost flash solution. They trigger easily using my D40 with a SB400 in manual flash mode (even with the lowest power setting). One other thing not mentioned is they do include PC sync cords.

Works fine

I bought two of the units to use in setting up for taking pictures of church members for a church directory. The units work fine and have a bit more output than I thought they would have. Plenty to bounce off the ceiling or wall or in our case, a piece of poster board. It's too early to offer an opinion about the durability.

Excellent!

Very-very-nice strobe! Use it to light my home-made softbox. The strobe is really powerful, so I either move the softbox further or add additional layers inside. Recharge time is around 3 or 4 sec, which is fast enough for me. I use a cheap wireless trigger to sync the strobe with the camera - works just fine! Planning to buy another one to light the background. Don't see any cons, besides the fact that you can't reduce the output, but it would be silly to expect this for such a price :)

Good value in a basic fill flash.

If they were smart, Adorama would list the umbrella/socket in the accessories list.

Update to my previous review

Had a pair of these AC Master slaves setup on a lightbox to do product shots for [...]. Last night one of them made a loud popping sound and wouldn't fire again. Sounds like the capacitor blew as the strobe tube didn't look burned or damaged. Kind of a bummer, but I'm afraid to waste money on another one.

Good cheap light

Very versatile, quick recycling little lights. Extremely sensitive and will trigger off my Canon S70 flash set at -2 stops flash comp. The PC sync is a great feature as well. I have a pair of these in cheap desk lamp clamps pointed at a 26" light box. And I just plug in the PC cord to my Canon 40D, F16 at ISO 100 gives the perfect exposure.

good cheap fun learning tool

I use it with one to three AC slave Mates. The PC cord is kinda' frail. An inexpensive way to learn some basic lighting concepts and have some fun. I had ordered some colered lenses to go with but they didn't fit, there had been a design change and the lens was too small if I remember. No, they aren't pro lights but a lot of fun for the money.

Love IT! and I plan on buying more.

I purchased two of these as an inexpensive start to a studio and I am very pleased with the results. They have given me consistant results and for the most part are very reliable. They are so easy to use once you figure out the exposures and placement that it will be along time before I make the jump to more expensive studio lighting. Only bad thing is that there is no modeling light. I would suggest that you purchase the filter kit for this flash for some really great lighting effects.

Very pleased

I bought two of the LATCMS, plus one of the JTS-20 AC slave strobes. All three exceeded my expectations. My only concern was that the house brand LTACMS lamps were marked "100 V" and I have 120 Volt service. [...] I decided to plug them in for 8 hours and see if they went POOF. They seem perfectly content. Like the JTS-20, they trigger if they are even remotely within sight of another flash, even facing the wrong way from the master flash. I am totally impressed with their sensitivity, especially for such a low price item.
