24v Garden fence lights - series or parallel??

[James]

Well that is something sorely lacking in this day and age judging by some of the lash ups we see on here.
Same base for 12v or 230v? Hardly idiot-proof, is it?

Edison screw base is used with lamps of many voltages and has been for a long time, I often come across them in machines using 24v, 50v or 110v lamps.

alas, every now and then as you suggest a customer will buy some replacement lamps (230v) from the local shop, screw them in and then call me because they don't work.

Could verify whether this calculations are well for solar panels that may be added in the future.I mean can I do this calculation for the installation and add more panels whether it is required?

That is confusing. (just looked at the website)
What is to stop someone inserting this 12v /24v lamp into a 230v lampholder?
That's why there is different cap types

Nothing stops someone putting it in a 230V lampholder, but that's not any different to 110V, 24V or 12V ES lamps, BC lamps or any of the other standard lamp bases used for different voltage lamps.

Voltage is not the reason for different lampholder types.
Some lampholders are only rated for ELV such as the gx5.3 lampholder used for MR16 lamps.

Thanks for all the responses guys, for the sake of closure and anyone reading this in the future, this is what I did and what the results were.

I originally used this DC-DC 12v to 24v Step Up Converter and cabled the LED bulbs in parallel which did work ok, but I actually had to change the step up Converter to a different type because the first one I used had a huge inrush current which would trip my 10a WiFi relay.

Then, last week, I noticed the 12v to 24v step up converter had stopped working, so out of curiousity I tried connecting the string of lights directly to the 12v supply (which, I admit I should have tried at the beginning of the project) and it worked!
I haven't noticed any difference in the brightness, the whole string of lights are nice and evenly bright, they do however use a little more current, 5.5 amps @ 12v compared with 4.8 amps @ 24v and no inrush current high enough to trip the WiFi relay.

All 10 of the LEDs are still working 1.5 years later so I do highly recommend them.
