ok now i know what you are talking about the charging of the (caps) in the driver. what will i see or how do i check to see if thay are all coming on at the same time. with the rapid controler the leds all come on a the same time and go off at the same time. now with that said after turning the power is turned off to the drivers i get a flash from the leds, but not all at the same time, just one at a time. so that must be the (caps) discharging. so do thay charge in the same order????? and if so i should be ok???
thanks
If the leds are all coming on at the same time that means the drivers are all firing up at the same time I would think. They may flash at different times when they go off but the initial inrush current to charge them would/should all happen essentially at the same time. And as Acrylic51 mentioned an even bigger concern than the inrush current is the harmonics that all of those drivers produce. The actual damage that can be caused is not always apparent. It could mean you may start seeing other electrical appliances on the same circuit start to crap out well before there time. And the continuous heat that is produced would be slowly degrading the wiring in your home. How long is not really known it just all depends on different variables in your particular situation. It could just simply mean that the wiring in your walls lasts only 20 years instead of 30. Or it could mean that your house may potentially catch fire a year from now. Or you may find that your breaker starts triping every time the fixture fires up a month from now. No way to really know for sure, just saying that the potential for these things is real and it is there. So I'm of the mindset that if it can be built safer then why not just do it that way.

I would think the sudden "bang" on the circuit would actually case the breaker itself to go crazy......Meaning the switch itself will get a bit sloppy, and the breaker short/melt. I'd be curious as to putting a temp gun on the breaker before they fire, and immediately after they fire. Corey is correct in explaining what I was eluding to about the harmonics. Your other electrical appliances might take the brunt of the in rush. That is why you see that only on the smallest builds usually the ELN's are used.....

Are the drivers all on the same circuit or do you have them broken up on different circuits?
yes all the drivers are on the same circuit, but i think that wall is on a circuit by on it's on because of the tank.
i built the house and did most of the wiring so i am checking to see if i ran that wall on it's on, it's been eight years????

ok, when in doubt, throw it out. safety first!!!!!!!!!! i do not want to take any chances. so what drivers do you recommend.
and thanks for making me aware of this.
thanks for the help
better safe than very sorry!!!!!!!!!!!!!

Wow!!!!! No one said to ditch the lights.....Just don't put all the drivers on the same timers or what not....That way in the event of a power outage they all don't fire at the same time....Try really staggering the drivers coming on....

not ditching the lights maybe just the drivers, and sure how more that one timers will help in a power outage, correct if i'm wrong, if i have one or three timers in the middle of the timed day for the tank thay will all come back on at the same time
the start time for each timer will be the only staggering of the drivers, right?
again better safe than sorry
and you are helping very much and if this is not safe i will not take any chances on my family

You'd have a to make a few modifications to the wiring scheme but you could run all of those leds with just two of the HLG drivers. It would simply mean converting over to running everything in parallel strings.

that would not be a big thing to do. but i may be okay, the leds are wired in series in groups of 14 then 13 then14 then 13 and so on and so on, same with the white and blue the red is in groups of 5 in series.

Can you tell me exactly what leds you are using for your whites and blues, also which reds? That way we can see what type of forward voltage you'll need to help pic out the right driver. Off the top of my head I'm thinking two of the HLG 185-48B's and possibly keeping just one of the ELN 60-48's that you already have to drive all of the reds.

True!!!!! Forgot about the power outage scenario......but would work on day to day, but strange things can happen during the day. Agree with Corey on the HLG would be the choice of drivers. Shouldn't be super hard to swap the drivers. Would have to balance your strings of LEDs though, and as Corey mentioned some modifications to the wiring.

I did have them spec'd running the XP-G's but don't recall off the top of my head my wiring scheme down to the details.....I think he'd still be able to run 13-14 per string, but depends on the LEDs....

the LEDs that i am running are XP-G R5 cool white and the XP-E royal blue, there is no part # for the red but thay are 3w LEDs.
i am willing to change to the HLG drivers i think the wiring scheme you did on one of you post was using the XP-Gs in strings of 14 i will have to go look.
so it looks like the HLG-185H-48B is the way to go i should have gone that way to start with, i was thinking that i would go the way of the ELNs so if one went down i would still have some light, but if that is not safe, the HLGs is the way to go.
thanks for the help
i need to go look the setup to see if i need more than two dirvers

the supplier that i got the ELN drivers from also has the HLG drivers i working to see if thay will do a swap for me. that would make us fill alot better.

That is good news. Now the only thing you have to remember with the 42B's is that you will only be able to run a maximum of 42vF instead of 48. So you're probably not going to be able to run 13-14 per string.

I think I calculated it out on the XP-G's at 12 on the 42's.....I think that's why I bounced back and forth between the 42's and 48's.....

Should be fine on the xpg's running 12 as long as he stays around 1000mA or under. The xpe's he would be pushing the drivers at maximum. Even at 700mA it doesn't leave alot of room for any leds that may be running out of spec.
242bats: Can you contact your supplier and ask him if there is any way that he can track down the 48B's for you? I know they are a little harder to come by so it might take more time to get them. But it would save you from having to change the configuration of your leds around.

not having luck with the supplier and 48B, i would just keep what i have and get the drivers from an other supplier but i can not find the drivers in stock
do one of you know of a supplier that may have two in stock

Shawn was speaking with a contact over at Jameco Electronics. He forwarded me an email of a response that he got from them stating that they would have a shipment of the HLG 185-48B's in like in the third week in July. So you may want to shoot them an email before they sell out.
