No, sorry!
Unfortunately we do not stock a warm white version.
It is recommended to either use the spike or the screws to install the unit.
It is 12 Lumens.
The lights screw-down via the screw holes around the outside of the light. Sorry that it is not shown in the video. However the full instructions state how to fix them to decking.
No, the panel is on top so they will need to be facing the sun and not vertical.
Yes they can. We are based in Harpenden, but we are not open to the public as we are not a retail premiss, all orders need to be online or over the phone.
They can be stakes into gravel, as longs as there is something for the stake to go into (grass etc)
These can be drilled/screwed down, however we would not recommend adhesive, as it may not be strong enough to hold the light in place.
