Can a 150w outside PIR light be upgraded to a 300w

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.

if the fitting is rated 150w max, no!

The extra heat will probably fry the fitting. I installed a 500w one, working from a ladder recently. Consequently I was right it front of it & very close.

Whilst testing it & adjusting the switches it bloody near set my fleece alight.

These things give off a lot of heat.

yep. About 499W of it ;-)

There is no faster way of burning money than to fit a half kilo-watt electric fire on the outside of you house, and letting the squirrels decide when to turn it on. :-)

to dawn low energy lamp for security lighting and a 500W floodlight for the infrequent times loading and the like is done.

If high levels of light are often needed a sodium lamp would be better.

ones are all 118mm, not 78mm long as the 150w. Never mind.

Whilst on the topic of PIR lights I am trying to find a white PIR light that can be fitted to the outside wall but angled so the light is pointing directly downwards. Most of the current ones are fancy (not the old square / rectangular lamps) and cannot be angled directly down. Can only seem to find the black ones.

It's handy for people with more money than sense, who don't have space for a yacht.

No. In addition to the other comments, a 300W bulb is longer.

As other people have said, 300W & 500W bulbs are a different length to the
