@rkymtnman It was because he ate the salad on a blue table cloth, maybe you didn't know, blue is the middle colour in the Russian flag...

How much did you pay for each 3950? I don't know why you would buy a CREE in 2017... There are plenty of cheaper alternatives

And if it doesnt you can eat your words. Likewise il do the same if it does.

@fjbudboy I received 3 pms, + goofy, + 1 other saying they are switching on more than 5 Drivers at once. Also have heard many many times the spec sheet is generous. Because of that, Il go by the actual useage results. Il be sure to post my results when I get them

@fjbudboy I hear what your saying, however take the spec wattage - states 239W, but its general consensus here that most(if not everybody) gets around 250W out of the driver.

@goofy81 I got the exact vibe. Thanks for speaking the truth mate. your real answer is more credible than majority of the theoretical bs posted...

Just wondering guys. Buying 20 timers and setting each one to start 30 seconds from its previous should work right? No need for advanced electrics?

So the reason meanwell limits only 2 drivers per Breaker B type is because its likely to trip our electricity, not because it will damage the drivers using more? In that case if we had unlimited Amperage/voltage breakers, we could power 200 drivers at once?

@guy_incognito251 https://www.racksolutions.co.uk/vertical-rack-mount-power-strips-8.html These guys sell them for much cheaper, they have surge protection but I dont know about sequencial startup... £40 for 8 way.

@DaveInCave Whilst hiring an electritian to change over the breakers maybe one option, Im sure there will be many other less invasive alternatives to this problem... Instead of hiring an electrian and paying that much, its better to just buy 10x timers... Perhaps using a Contactor with...

In this case guys, is there a smarter way to power on two at a time from one power source? Ideally Id rather not use 5-10 timers all 2 mins apart, perhaps there is a relay or connector that can be used?

@CobKits, do you know if thats a conservative number(as its meanwell) Also, why it's only 4? seems like we have loads of amperage at the socket going unused...

Have quite alot of Catholic Church's thankfully, they probably run 13A too.

In UK, we have single sockets capable of atleast 13A at 240V = 3100W Is there any issue with powering on all at once our 10 250w = 2500w drivers? Drivers would be Manwell HLG 240

May god bless Mahiluana

Kapton tape sounds the best way to go, when you wanna move/change/reuse cob, just peel it back...

@ohdang I think you would get significantly better gains by using a fan than using a radiator. I dont think its a simple as a fridge cools things... Fridges probably work based on the items inside being kept inside over a long period of time, as your constantly moving your water through a pump...

@The Dawg Thanks for pointing out that additional field. Interesting that the HLG over voltage protection is 188 ~ 206V and the ELG 192 ~ 216V Wouldn't the 4v gain from the lowest Over Protection Voltage with the ELG be better than the 2v gain from the Open Circuit Voltage?

@CobKits I made some queries as to why the ELG are cheaper/lighter/smaller than the HLG. The answers which came back multiple times is that, the ELG are made on a automatic production line and come with less warranty (5 years).

@The Dawg Hey, You said overvoltage kicked in at 160v when that drivers stated range is 71v - 143v, also you are running it above the 1.4mA range too... With that said, Do you think using the ELG-240-C1400A (not HLG) I would be able to run 5 COBS at 36v each(180v total), at 1400mA - 50w...
