Led Drivers - One Per Lamp?

[430Wedge]

I have 2 pairs of LED lamp fittings, each fitting rated at 350mA, and each pair of fittings is wired in series from a single LED constant current driver rated at 350mA (per manufacturer / supplier instructions). Light output is not as bright as I had expected - are these ratings compatible with each other, or do I need a single driver per individual lamp fitting?

First thing to check if they are not as bright as you expected....

and you have followed the manufactures instructions....

Is what is the specified lumen output of the lamps.....

compared to the lumen's of lamps that were there before...

or the required light levels you are looking for..

Does the driver have 0-10V dimming and if yes have you connected to that by mistake, which will produce very low light level.

The driver is specified as 19-35V, so I guess that may be the answer to my question (2 x 12V lamps per driver).

???

19v to 35v....

2x12v= 24v

24v IS between 19v to 35v .....

so why would that be your problem???????

Clumsily worded by me. The original question being do I need a driver for each lamp, and the answer (as you have confirmed) is no.

Many thanks
