Horrible experience with Briteks! - (solved?)

Major problems:

I used two Rostronics soft boxes 600s + two 600s (without softbox) as key light, and two 1000s.  I received them a few days prior and tested them for about an hour.  We had a long session Saturday.  It was an interview setup.  A bulb in one softbox went out after about 6 hours.  Then one of the 1000s  made a "clank" noise.  Turned out the bulb simply fell out and hit the glass!   ??? A few hours later, the other 1000 did the same thing, except one of the posts the bulb attaches to, was completely melted and a ceramic piece broke.  Then, an hour later, the other 1000 made the "clank" noise again, but this time, the metal post that holds in the bulb and powers it also melted. :-/  ( I suddenly had no 1000s!)

One person helping me was a film maker from Europe.  He was initially real impressed with the lights.  By the end, he didn't want to buy them anymore!  I told him that I did "research" and that these came highly recommended.

I was very disappointed, to say the least....  I hadn't planned for that many failures, but we did make it through the shoot by being creative with the remaining lighting.  We stopped using three cameras and could only shoot one talent, pretending to have both talking to each other.  The light changed, of course, but, nothing that can't be fixed in post (I hope.)

It was important to me to impress this client, but oh well.  The next day, ABC showed up to film a documentary on the making of our documentary. (ABC - Australia Broadcasting, not our ABC!  They flew all the way from Australia to interview the author and shoot us editing the documentary!)
Still, after a few days all went well, luckily.  Client is thrilled.

I talked to Tom and he says he's only seen this problem once before.  He's sending two replacement 1000s.

I'm hoping that this was simply bad luck and remain hopeful.  I'm going to test any new lights by keeping them on for about 12 hours, and turning them on/off every few hours.  The problems always occured after turning them off, and after 15 minutes back on.

I hope people are posting their problems with these lights.  They certainly aren't made at the level of quality of some more expensive lights and it was a b*tch gelling them.  (I'll do a search and hopefully find posts that suggest third party scrims and gel holders.)

Tom is very amiable, and customer oriented.  I hope I just had bad luck.  Tom is sending me two replacements, so I'll test them thoroughly this time!

I still have faith in everyone elses enthusiasm for these lights, and the soft boxes gave a wonderful light.  When they work, I'm impressed.  Impressed enough to buy two HMI Dayphotos from Tom even after this problem.

Re: Horrible experience with Briteks!

Wow -- that is indeed horrible. I guess at the ridiculously low price point, something gets cut, and maybe in your case it was quality control!

I currently only have two of the 250's and two of the HMI's. I've used three of the 1000 open-face units (square-face non-focusable, not the round ones on rostronics' site) for 12-hour shoots, on & off, with no problems, and I've used my 250's for multi-hour shoots with no problems. The HMI's seem less rock-solid in their build quality, but I'm at least the third owner on those so I don't attribute anything to the original quality so much as I do to that they've been used for years.

I do very much hope that your new lights solve the problems you encountered, and I guess we should put a caveat on anyone getting these lights that they should test them thoroughly before relying on them for a production.

Barry,

Tom says he does some very simple testing. Do you think my idea of running them for 12 hours is enough? (Turning on and off once in a while?)

Re: Horrible experience with Briteks!

Yeah, but definitely let 'em go for a long time in the first run, you want them to get as blazingly hot as they can, so maybe 8 hours for the first run, then you can try the on-off, although I'd never do an immediate restart (turning it off and then immediately back on) -- that just sounds like trouble. I'd always allow a few minutes before restrike.

this is why i wait 2-3 months before i buy anything recomended on this site (or others for that matter) :p

Re: Horrible experience with Briteks!

Jeez man, that's terrible! It's interesting that the 600's were no trouble and the 1K's were a complete washout. I just orderd from Tom and was about to order some more, but I think I'll hang on for a bit to see what other problems arise.

Is there any possibility that the 1K lamps (bulbs) are the problem - that they're not U.S. made. Maybe putting a regular Sylvania or GE lamp in would do the trick. I've bought household lamps from Ikea in the past with their third world lamps included and the holders always overheat and break. I LOVE Ikea, but I will never buy another light fixture from them.

I just posted on another thread that I know Mathews make scrims and gel holders from 5" to 13 1/2" in 13 steps (B&H BTW). I'm sure there's a size in there to fit the 600's, but I don't know how big the 1K is - it looks really big.

Keep us all posted, please.

Re: Horrible experience with Briteks!

Tom thought that the bulb in the 600 that went out might be due to shipping. It may even be that the others were damaged in shipping. He swears he's only seen the problem in one other light.

The bulbs look fine, its the metal posts on the light that is melting!

Re: Horrible experience with Briteks! - (solved?)

I just received an email from Tom at Rostronics:

He says:

I talked to the manufacture and they seem to think that the bulbs aregetting loose in shipping and arcing to the side of the clips. I think I'll be shipping the lights without the bulbs installed and I think this should solve the problem. They said there should be no problem running the lights
for 10 hours at a time, and there should be no problem turning the lights on and off.
 
Re: Horrible experience with Briteks! - (solved?)

That does sound to me, from the description of the problem, to be an issue of arcing. THere shouldn't be enough heat in the light to be melting metal anywhere, but I'm also surprised that these lights didn't trip whatever circuit they were on if they were indeed arcing.

Ideally, you'd like to think that all that excess wattage is going back down the ground, and not...say, for example, back into the metalic touchable parts of the lamp.
 
Re: Horrible experience with Briteks! - (solved?)

my bulbs fell out also, but they have been working fine since i pushed them back in. I had them on for a full 8 hours taking pictures of medical equipment in a hot basement and nothing happened.
 
Re: Horrible experience with Briteks! - (solved?)

Your bulbs fell out also?

So, you simply unscrewed the glass front put the bulb back in, re-attached the glass plate and continued with your shoot?

A loss of time, but I'm wondering about the connection, because I experienced the bulb falling out. If it is loose it will arc and maybe fall out. A bit disconcerting.

I'll test the new ones!

Re: Horrible experience with Briteks! - (solved?)

yeah it seemed that they are only held on by a little clip that holds the prongs. I pushed them in but it looked like the connection did not have a ceramic casing. to keep it from burning up or arcing out.
im going to turn mine on again this weekend and leave them on just to test.
 
Re: Horrible experience with Briteks! - (solved?)

..let us know for sure.. ive been eyeballing the 500-switch-1000's alot, and it woud sure be embarrasing, and bad to have somthing burning up in the middle of an important client shoot. :-/
