I've got 4 PIR lights outside the house and two of the bulbs have died. Trouble is they're 15 feet up and I hate heights, even if I had a ladder which I don't. I can get someone in to change the bulbs but do I need to first get the old bulbs out to see what they are or can I take a stab at buying new bulbs and hope? That would need two visits and more cost.
Google suggests they're going to be R7 118mm halogen bulbs but these are available in various wattages. If I go for 300w bulbs might some lights not take these or is it a safe bet?
