Watt Ballast HPS vs LED

[Amnesialocal]

Hi all,

I hope this is the right place to post.

I understood ( please correct me if wrong), that an hps light consume more than what defined by the bulb wattage.

For example a 600w with magnetic ballast consume 660w while with digital 620w....( I read this in internet).

Also I heard someone saying that at the wall for HPS always is required to add 10-20% more ( 60-120w) 

 

Can someone clarify the above? Is there a table to understand which wattage? (125-250-400?)

 

Also can someone clarify if an LED say 200w at the wall is 200w or 220-240w?

 

Many thanks in advance

I think digital hps ballast is 650w of total,600w led is 610w or summin like that.

 

Your socket is 3kw,should be

Amnesiasocial. I would get a socket  power meter. They are quite cheap. You can nail down what each appliance costs.

If you buy a decent LED light that claims to be 600W then then that is what it should draw from the socket.

 

Or the manufacturer is lying to you.

 

@catweazle1 A socket meter is a good shout.

The other thing to factor in is HID bulb replacement cost every season or two.

I've got Two of them, plugged into the wall beside me, as I type!!! Do try to keep up, fukka!

 

Actually, mate? Grab one (or two) then, we can hunker down in PM, trying to figure out how to Work the damn things! Christ! They ~ potentially ~ spew out more data than Intel could handle! I'm scared of mine!

Isn't it like 610w from 600w led?

It should be sold as a 610W light, then, shouldn't it?

 

Unless the LED Gods have rewritten power usage!

I think manufacturers like to show straightforward numbers. It's only an error of less than 2%.
