You can try a 300watt bulb but the light fitting might only be built for a
maximum of 150watt which means the fitting will start to melt.
check to see if it states maximum 150watt.

Hi guys

I purchased the following outside light a couple of months ago

https://www.screwfix.com/prods/99280...loodlight-150W

I am now wishing I had opted for the 300w version. Can I just upgrade the
bulb to a 300w or will there be some internal differences?

Thanks
