I have a single, generation 1 lightwave dimmer controlling a bathroom – with an extractor fan and 4 x GU10 downlights. Need to change to the warmest possible, min 2700k and 50w equivalent output.
I know there’s a bulb compatibility list on the LW website which mainly recommends Megaman bulbs, since these are hideously expensive, I wanted to know if any others will work.
I was about to order these: TCP Spotlight GU10 LED Light Bulbs 5 W = 50 W Equivalent 240 v 2700K Warm White, Pack of 6 [Energy Class A+] https://www.amazon.co.uk/gp/product/B01FIRJINY/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 but unsure if they will work.
Does my extractor fan play into the compatibility issue? All works fine on the current halogens.
Amazon link if possible pls.
The link you provided says those bulbs are non-dimmable, so I’d guess they won’t work.
Hi thanks for your reply,
ok I see that now on the image, but not in the product description. Thanks!
Can anyone recommend LED’s they know have worked.?
Must be 2700k
I had problems with some “recommended” Megaman units which never fully went off.
Replaced them on a punt with these from Screwfix and was pleasantly surprised that they cured the problem and work fine.
Not the lowest dimming level compared to halogens, but that’s LEDs for you in general I think.
Ah thank you very much for the link and recommendation!
Geez 15 quid! But I think I’ll give those a go.
A limited range of dimming is fine for the room i need to do, as it’s a bathroom.
If anyone else has had ‘real’ experience of what works (and recent experience too) it would be great too.
I emailed Lightwave and they just said Aurora bulbs.
I thought the price wasn’t too bad actually. £3 a unit was cheaper than the rubbish Megaman units I had previously.
And a further update – I also had bought 10 Megaman units for my kitchen as well as the units above which were for my landing corridor. These didn’t suffer from dimming issues which I put down to the fact that there were 10 of them, rather than 4 in above scenario.
However, four of them have now failed within weeks of each other and all less than 18 months usage! Very poor, and will never use Megaman again now. Went and got another 5 pack of the Screwfix units.
EDIT: PS, No affiliation with Screwfix, just saw it looks rather pushy!
Just wanted to share my experience, as I know it’s VERY difficult finding good info on this topic. Any other feedback you get would be welcome all round I think.
Many of the dimmable GU10s from LEDhut work well with the gen 1 dimmers. I have just two lamps on a dimmer that work but I bought these a while ago and they’ve now been discontinued. I’d suggest you give these a go if you are using four on one dimmer: https://www.ledhut.co.uk/spot-lights/gu10-led-bulbs/5w-gu10-led-spotlight-v2-warm-white-dimmable.htm If they don’t work you can return them.
All that said, the issue could be with the fan. I think these have compatibility problems with most dimmers.Running RFXCom with Domoticz on raspberry pi3. LWRF dimmer switches, PIRs and plug sockets. Some Homeeasy switches, harmony hub controlling AV and air con. Geofencing with Pilot app. Tado for heating and cooling.
miken – didn’t see that was a 5-pack! Ok that’s a really good price. The lumens are a bit low for me in this case. But great to know they work.
markk – thanks for posting yours LEDHut link, will have a look at those now.
An update; I got in contact with energybulbs.co.uk who sell LW switches and gear – plus a a broad range of LED bulbs.
So I asked them and they said (no surprise) Megaman 6W Dimmable GU10 LED – Warm White. These had a high lumens output and price was ok at £6.75.
So I fitted them in spare bathroom today. As mentioned in my OP there is a also an extractor fan running off this circuit, controlled by a Gen 1 LW dimmer single gang.
One by one I swapped the halogens for the LED and all ok – until I had 4 of 4 LEDs. The lights went out after 6-8 mins. The switch must not like the LED and extractor combo and shut down.
It went back on but I don’t want to blow the switch so I actually put 1x halogen back in. Which seems to have settled things. The 3 x LED + 1 x Halogen seems to run and run.
These LEDs also dim down to a reasonably low level and also switch completely off too.
I am sure it’s all sine waves and stuff I don’t understand but any experts out there who could tell me a fix to run the 4 x LEDs with the extractor?
Thanks a lot.
I’m currently struggling with 3 LED’s and an extractor fan on a 2 gang switch. Was actually working fine prior to latest firmware update (3rd Dec)!
I’ve found the B&Q sell a range of Diall LED bulbs at reasonable prices and they do dimmable versions in most popular whites.
Sorry guys but the output from these dimmers is just not what a motor needs to make it spin. You may find it works initially and in that sense you are lucky to not cause immediate damage to the fan, the switch or both. If you’re using gen2 then you can overcome this by powering the fan with a gen1 relay linked via the app to the the particular gang on the switch
