Growing light products from the Netherlands? (5,5)

'netherlands?' is the definition.
I know nothing about this answer so I can't tell whether this works.

'growing light products from the' is the wordplay.
I cannot quite understand how this works, but
'light' could be 'bulb' (bulb is a kind of light) and 'bulb' is found within the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
This explanation may well be incorrect...

Can you help me to learn more?
