Here you can see a solar garden light, a USB powered light and a light with a rechargeable unit in the base.
These are all set to white and you can see the difference in colour temperature based on the type of LED that’s installed in each version.
The difference in height is due to the location and type of light. The solar unit is in the top. The USB unit is very thin and at the bottom, the rechargeable unit is also at the bottom but takes up more space as it needs the rechargeable batteries and charging circuitry. in terms of the shade itself, there is not much difference.
Below is a comparison table so you can choose the light that suits you best.
Note: This table is only applicable where the product has a choice of these options. Not all lights come in all 3 versions but I am adding all the time
