How to connect 10W LEDs?

[juanico]

Hi guys

I want to make a LED light with 10 pieces 10W LED.
Which is the best way to connect them?

1. 10 x 10W Led parallel connection with driver (10V, 10A)
2. 10 x 10W Led series connection with driver (100V, 1A)

What are the differences in both options?
Whats better?

1A...you burn less current.

I have the 3W at 1A total driving current. Works like a breeze. Get the Meanwell driver - I think they have a reseller in Bangalore.

what is the advantage?
consumption is U x I = 100W in both cases.

there is also a meanwell dealer in nehru place, bought some drivers there already

Can you post datasheet of led?

For safety reasons best config is series, so if single led fails, rest are safe too.

hahaha...no-name-no type-id -no-datasheet...

but ok, series it is

[saikumar]

Can you count number of small minute white dots in it? Are they in series or parallel?

[saikumar]

most of them should be same specs, so assume you got this one

and 9.6-11V is optimum, with 900mA. So you are good that way.
So 2nd option should still hold good. but AFAIK, there arent many selling 100V drivers.

so maybe a driver with 48V/1.8A...so it would be 2 parallel circuits with 4-5 LED in series each...right?

Yes,5series/2parallel. Worth having a fuse on each as you have parallel.

fuses? why? which specs?
