Resistor value 16k to gnd. in photo? Is that a blue band?And what is the resistor value - we can probably decode that to a current setting.
Thats useful. So the lamp needs 605mA and will have about 115V across it.Here we go, had on my old phone.
These are coming up in the £50.00 range, is this cheap, and why the 500ma over 700ma?
The 500mA version of this range is the nearest i can see for a fixed output, assuming they dont want dimming.
They are cheap enough to give it a try
Yes I think it would. Also it's likely that the programming resistor from the old one could be transferred to this. But I don't know if any of the other control terminals, Dali etc. need to be left disconnected (or not) once the o/p current is set.
500mA is less than 600mA so not going to stress the LEDS,Thank you all again for your time on this matter.

what do you recon on the following;
Looks good to me. Gives 550mA with current selecting resistor of 0 ohms, ie a link, so you don't need to buy a programming resistor! Seems good to go.Tridonic Non-SELV 75W Constant Current LED Driver (250-550mA)
This driver has been designed with a low profile metal casing and has an IP20 level of protection. A constant current LED driver with an adustable output current between 250 and 550mA.www.bltdirect.com
Any thoughts on above
