Led and halogen

Can you have a mix of led and halogen bulbs in same light fitting.
Got g9 halogen in but want to start with eco led ones

Yes mate you can, as long as it’s not on a dimmer otherwise you will need Dimmable led gu10 bulbs

I have a pir light switch on my stairs and it will not light with all leds in as it need more power drawn to kick in
so I have to have 1 halogen installed

you can mix them.

Not advisable depending on your dimming requirements.

on and off will be fine though.

But why not just use LED and save your energy bill. If you are overcoming a minimum load issue with a dimmer then it can work, but again it will effect your dimming. if dimming is the reason for the mixture you are better off changing the dimmer module to a zano or similar.

I've seen several occasions where it is not possible to install all LEDs. Sometimes they don't light at all, and some times they don't turn off.
The latter case is the worse, if the halogen burns the LEDs stay on and you can't turn them off.

In these cases is best to replace the dimmer / driver.

Also some times, especially with dimmable G4, the operating voltage is AC 12V or 24V (not DC). And installing LEDs might not work at all, or work for short period and then burn out. In these occasions the AC transformer should be replaced with a LED driver module.

I bought my dad about 6 g9 led bulbs to replace his halogen. I bought one and tried it whilst mixing it with the other g9's and it seemed fine but when we replaced all six they found the the bulbs where not as bright and as it was a dark house so they changed back. These where something like 5 or 6w 72smd. I would go for as high a wattage as you can. You will still save a the g9 he had where 40w.

Not using a dimmer so should be ok. It's for a friend and she needs about 10 so gonna swap them gradually.

Surely its cheaper to buy in bulk?

£3 each bulb

And she is a pensioner

pack of 10, 14.99 at screwfix

Honestly, you get what you pay for with those screwfix bulbs.

Spend a few more quid and get aurora enlights 2700k (nice warm white) and I think they also meet Part L lumens rating

Approx £3 - £4 each non dimmable.

Or if flush get the Osram parathom 7.2w 2700k wide 60 (7.something watts) not the 5w model

ok guys thank, got some decent bulbs to try out.

It depends on the transformers fitted as well whether you can have halogen or LED doesn't it.
Obviously if they have been in a while then you may have transformers that are only fit for halogen lights.

They have been in for a while so will try 2 bulds

Well that depends if the lamps are 230v or 12v (transformers).

Most (not all), are GU10 which are mains dimmable 230v Lamps.

These have a built in driver inside the small end of the lamp where the contacts are made to the mains supply. LEDS have a 50,000 hour life span. but the drivers inside do not, this is really frustrating because the 50,000 hours is misleading people into buying LED Lamps thinking they will last a life time. That is also why I mentioned buying decent quality lamps as the drivers will have a better manufacturing process.

Transformers for halogens (12v) old styles, can rarely be used for LED Lamps - this is because they usually have a 20-60watt minimum and maximum wattage output. Notice the 20W part, as you will be aware most LEDS are around the 5w mark making old transformers useless or will flicker and cause all sorts of weirdness.

On another note I have been doing some design works lately with a very large company, and got told off for calling LAMPS - Bulbs lol.

Apparently bulbs grow in the ground and lamps go on fittings lmao.
