Is anyone else having issues with strobe not working that were bought from DIY LED express? Mine are going out on me this year and they are new. Used in 3 shows and are now going out on me.

Any issues with yours?

I don't have a solution for you but I am curious what type of strobes you are using. Xenon (I or U type) or LED?

I ordered both I and U Xenon strobes

Hey fun stick,

Me to. I bought 25 U strobes during the January 2015 pre sale and installed them last week.

12 have failed so far :-(

I opened one up, and a component was roasted. I haven't had time to troubleshoot, but intend to find the bad component to see about repairing them.

Have you opened any?

Have you found a different vendor or strobe to use?

I did open one up and the board is a little burnt or the strobe itself is crusted over. If you come across a component that went bad please let me know so I may try to repair it. So far I haven't received any refunds but I am working with the vendor. They do acknowledge that this was a bad year for strobes and they are exploring other manufactures.

Okay, similar experience.

Bought 25, displayed 20 and 11 have failed within 5days of putting them on.

They are only lit for 10seconds once every 2 minutes and didnt run them in the rain.

Oh great... I bought 30 of them and I had enough from last year so I wasn't going to run these but rather keep them for spares. I am thinking perhaps I need to burn them in .... so to speak and return the bad ones.. .

Edit: I sent an email also asking what they are going to do about the problem. Lets see how they step up. I am not really that interested in paying shipping back for parts that I paid shipping to me for that are defective. Perhaps they will do the wise thing and just replace them all and let us toss the bad ones in the e-waste. I would not put known bad product in my display.

With all that said.. since I have not opened mine, I can't say for sure I even got bad product.. but I am pre-emptively concerned from all the failures you guys are having.

I had a 25% failure rate. I'm not sure what the issue is but mine were sparking from on top the board. I had the first failures replaced. Even some of those had issues so I took some liquid black tape and dabbed around the area where it was sparking. This saved a number of them that were still semi working. I haven't been out in the yard to see how the rest are working. See the attached pic.

I had about 30% fail at this point. The company did refund my money on some. They are looking for new vendors as they acknowledge this is an issue.

Mine all worked 100% (25 of them) out of the box. Deployed 24 of them and then they failed. So unless you're going to soak them you're not going to find those which will fail.

Todd answered my email and said I could send mine back. I haven't opened my up and didn't plan on it until 2017... I told him I would rather keep them if they are not the ones that everyone is having trouble with..or unless he would warranty them in 2017 when I used them. Not sure what his answer is yet. He also didn't offer to pay shipping for the return of the possibly defective product... I paid $17 to get em and it would be about $23 to send them back on my account.. that would be $40 for a defective product that I never used.. I would have an issue with that..

With that said.. I still don't know if I have the same ones you guys are having issue with.. Mine are the ones that we bought on a presale for $3 each I think.

yea i dont think i will send them back either ..i am from canada so its a fortune to ship back ... but it would be nice to know witch batch are bad ,,the pre sale one or the after pre sale ...but i think they all come from the same supplier,, so they all bad ... but i could be wrong ...cheer

Possibly a little moisture causing it to arc over on the board.

This is the stuff we use to use to help control arcing on high voltage flyback transformers:

Some of my strobes failed this year also, the ones that are arcing to ground u just put some super glue over the copper chases and that fixed those. The ones I can't figure out is when they light in the base.

When you test them let them run for a minute. A short few seconds isn't always enough to do it.

Todd just replied to me, and I say great support offering refund on the failed units.

I've bought $100s of stuff from them so in the end they honored their side of this fiasco.


They've offered a refund in the failed units, so I hope they get the same from their suppliers since they're putting themselves on the block for this;

I had the same sparking on the initial batch and Todd (DIYLEDExpress) was great and replaced them. If I get any more like this I figured I'd try to fix it like you did (liquid tape or hot glue). But...how did you get it open? The lens appears to be threaded, but I couldn't budge it. Seems glued on solid. Is there a trick? Does it just unscrew if I use enough force? I was sure I would break it so I stopped trying.

Do they need any repair under the board? If I'm going to take the effort to open them up, makes sense to cover all the bases. Reddy, what is that dope on ebay like? Watery, syrupy? Dries hard, sticky, doesn't dry? Do you just brush it on?

I didn't do anything under the board. But if it's blinking under the board I don't know how to fix. I just covered the top with super glue to cover the chases.

I too have had multiple failures out of 20, 10 have failed. It is a board issue. I have 20 from another retailer that have a black octagonal base and have not had 1 failure in 3 years.

I have these strobes from Darryl, mine are U tube Xenon based.
I have had a 50% failure rate in the first year.
Obvious water intrusion.

In Houston, we have high humidity and a lot of rain this time of year. It was suggested when I first bought my strobes (6 years ago) that we drill two weep holes in the top of the strobe (two holes on either side of the end of the tube, away from the socket end), so that when they hang down, the moisture can run out. I also bought mine from Darryl, and had a couple of failures at first, but by drilling the holes I have lost 4 out of 30 over a 6 year period. I think that is a good failure rate. I'll find a pic and post.

The ones from DIYLEDEXPRESS were failing before even going outside. I screwed them in and turned the string on and 50% stopped working within 1min. I live in a dry climate so that may be why the other one work better.

The problem appears to be the high voltage pulse is finding a way to arc across the board instead of going to the tube.

Get liquid rubber and coat the board.

Ok.. offered a refund of the failed units.. so did you have to ship them back? If so, who paid to ship them back? who paid to ship them to you in the first place?

I my case I have no plans to even use these until 2017 so I asked Todd if these are from the same batch, and if so would he warranty them that year if I keep them or should I send them back.. I explained that i didn't care about 1 or 2 failures but 20-50% was not going to work. So...now assuming they are the same batch that you are having high fail rates on.. His response was that it would be best if I send them back and buy when I actually needed them.. So that is OK.. EXCEPT he wants me to pay shipping back to him.. because that is his policy. So that means I would be paying $40 in just round trip shipping for $90 worth of a defective batch of product that I never even took out of the box but was found to have a very high defect rate. I would not say that is such a great deal from a vendor.

I also said I will pay the shipping back if he refunds the original shipping charges.. I have not heard back from him yet but it has only been a few hours.. Somehow I am sure it will get worked out..I would be happy if he just replaced them with known good product and I would just toss these.. I would rather have good strobes than nothing at all for the $40.

With that said. Still don't know if they are from the bad batch.. but I assume they are...

In all honesty, a good vendor would investigate and if the fail rates where that high, they would recall the product and or refund and tell you to dispose of them. Being a retailer, he takes that chance with the product he sells. We all should have expectations that a vendor has vetted what they sells.. and should that not work out, stand behind mass defects including the cost to get them back if he needs to do that. I also hope he gets the return credit from his vendor, but again, as a retailer it is his responsibility to deal with that.

I know when I made DMX cards for the laser industry and sold them for a very small margin, I had an issue where someone in England got two cards that tested good here but for some reason had the wrong resistor packs in them. Those packs came out of a bag that came straight from a US vendor that had somehow put two different ones in the same bag... and the numbers were only one off. Our testing didn't show the particular issue they were having, but I paid FedEx international 2 day air to get them back and send him new ones. Yes.. lost my ass on that product for months because of those parts.. but I made it right by every single customer.. It wasn't the customer's fault and it wasn't just warranty failure. It was a manufacturing issue.. just like the strobes...

Perhaps I just have high expectations of vendors since I was once one myself.

Corona dope, is a generic term like super glue... From what I remember.. the stuff we used.. brushed on and was similar to liquid tape but was a little softer and has better high voltage insulating properties.

not sure what is going on but i am definitely going to test them in the garage this week end as i dont need them this year but if i used them next year the subject matter will be too far gone and over ..they are still in the box and let hope the failure is not that high ..more to fallow.. cheer

I bought 20 this year and have had 3 fail at this point. Still an unacceptable failure rate. After seeing that I can get a better effect with the strobe effect in nutcracker I will probably never use strobes again. It is obvious that the manufacture of these really screwed up somewhere. I also bought from DIYled express.

I have lots of these.. I have had them for a few years now. I usually get 1 or 2 failures a year but they don't seem to fail while out. Only seem to fail after I put them away for the season and pull them back out the next. Could be the water inside corrodes the internals... haven't really looked at them once they go bad..

Not as bright and very directional. But good if you plan around the short comings.

I have some of the pre-order strobes as well. Guess I should check them out.

That being said, I'm not worried.

Granted I'm not nearly as active as I used to be, but I don't recall anybody ever being dissatisfied with Todd's service. I do remember people blowing things out of proportion because they didn't give him tiime to figure out what was going on.

I also recall other vendors offering a 60-day warranty on an item you bought in July.

Just saying, give DIYLE a little time Unforutnate this happened, but by and large it's the vendor, not the product, that we stand behind.

Bought 10 this year and 2 have failed. One that's still working has a long lasting warm glow emitting from the base se real seconds after it is turned off.
