The company “Müller Licht” has apparently very favourable high-voltage-LED spots with acceptable quality of light – for example for bathroom recessed. This is not my assessment, but the judgment of a user, who himself had bought eight of these spots on my recommendation. Read here how it came to be.
I was thinking about already, to put some kind of universal LED buying advice in a blog post. Yet that would be measured for various reasons: because of the sheer volume, I have no complete overview of all relevant products on the market. Most vendors/manufacturers I learn what a maximum at random by the countless new releases, technical development preceded rapidly – a concrete “buying guides” stultified so probably within a few months.
Test lamps do I rarely made available and can also buy not all me; may have to recommend but “blind” no lamps/lights. What works great for one purpose/customer, can be a total flop for the other. My assessment of a particular LED lamp must not coincide with the majority of the clients and can therefore be worthless for many.
It looks better with special conversion and setting up projects, where recommendations and reviews of LED buyers/blog readers ‘ come in. Here, the chance is relatively large, that really can – help the helpless laymen (and others) like in this case:
It all started with a “HUKD” request
“I’m looking for recessed LED lighting for my bathroom. I’m really the Wolf, but the variety slays a really. So far could I find out that 230V-Strahler is not bad, because it requires no transformer. Spotlight will be built into 5-6. Would be great if someone would have a tip for me.”
So it was at the beginning of the month in the “HUKD”bargains-portal of “MyDealz”.There are recommended often LED special offers or requests made. And I give my mustard here in the blogthen – similar as for the readers questions to LED conversion projects. The presumption that man for new installations high-voltage-LED spots without external power supply should prefer, was ever quite right. Since the disclosures in this case appeared to thin to me but, I asked for the first time:
“How many square meters? What angle wanted (approximately 35 degrees such as halogen or wider)? Dimmable or not? Which color temperature (warm white, or rather “colder”)? How true to color? How much space is in the ceiling? What should it cost?”
The response of the people seeking advice:
“So, the bathroom has approximately 12 square metres. Since there should be a general lighting, a greater angle of advantage would be. The lamps must not necessarily be dimmable. Because the ceiling is not suspended yet, I’m quite flexible – as long you still can stand under it. :-)“
My basic recommendations
Okay, so you can start something. I had a similar situation three years ago at the redesign of my laundry room and so I posted these recommendations:
IP protection is usually in the bathroom that is negligiblewhen the spotlights are recessed in the ceiling and thus very far from the water tap away. Unfortunately, provided housing for all GU10 LED spots (partly because of the length, partly because the width of the head part) but not all fit for halogen spotlights. There, trying out is announced, except when offered complete housing/lamp combinations.
5 spots of â at least 200 lumens should be enough color temperaturearound 3000 Kelvin for 12 sqm, each with approximately 60 degreesbeam angle, (which is also a “warm white”) and a color rendering index of at least RA 80 (important, because especially the Lady world will not look like a dead body in the mirror – the bathroom several times a day finally and seriously appearance worked). Such high-quality LED spots will typically have about 4 Watt power consumption.
Swivel housing are not strictly necessary, because to the often low range in wide LED spots hardly makes a dent. Unfortunately there are but by Philips, OSRAM, LEDON, LCTW etc. almost consistently only spots with about 35 degrees beam angle or less (lies on the used package technology with superior lenses, which have wider radiating mostly front this SMD chips without additional optics).
Just search and nothing to buy, where the important data are called not credible (even nothing at all from dubious sources of eBay/China). To something like might work, perhaps this. I haven’t seen but even still both. “The assessment of the quality of light is stop also partly a matter of taste or different biological reasons.”
Somewhere else cheaper
Suggest an other user with the supplementary note volunteered:
” Voelkner nearly EUR 2 per item cheaper, currently shipping and again 5 EUR cheaper with promotion code “Wholesaleably“.” Once ordered for the above usage purpose (approx. 12 m², bathroom, 8 downlights) them. Thanks for the tip!”
This sounded promising but and so I expressed this please:
“Fine, maybe you could report later even your practical experience – preferably by E-mail to firstname.lastname@example.org and with photos.”
The judgment of the buyer
And actually came rushing today of this text and four images of Uwe for me in the mailbox :
“Advance three things: these are my first LEDs, so I am perhaps a little euphoric.” Second, If you want to publish anything of them, then please just stating my name or without attribution. Thirdly, The attached images are created by me. You can use them like in the context of your blog.
The body is one piece and white plastic (Picture left). The size corresponds exactly to which a halogen lamp, up on the plastic protective glass, which, is slightly curved in contrast to the halogen lamp -. The protective glass is somewhat structured, so – so my guess – better scatters the light.
The room is – as I said – a bathroom, 12 sqm, white walls, white ceiling, white tiles. The previous lighting consisted of eight down lights of â 35W in the plasterboard ceiling. Actually, the LEDs should correspond to a 25W-Halogen-Strahler in the brightness. But subjective first impression: same brightness slightly – visible only in direct comparison – colder light colour.
Three possible reasons for the perceived brightness of the LEDs:
- the old halogen spotlights have quite a few years under their belt, so no longer emit the full light output.
- the LEDs are an area light source, whereas the halogen lamps give off point-shaped light.
- due to the slightly colder (but pleasant) light color, the overall impression is subjectively brighter.
The light color is very natural – a color cast I cannot determine. Also the skin color is, of course, what is important in the bathroom.
If used an hour a day, a power savings of about €25 per year results roughly. This means that the purchase price is at least every two years back in there. And if the specified lifetime of the luminaires is true, I need no substitute in this life to buy more.
Here are the specifications according to the carton and label (section above):
Power: 3 W
Beam angle: 90 °
Light color: 3000 K (warm white)
Light output: 105 cd
Luminous flux: 240 lm
RA (CRI): > > 80
non – dimmable
Switching cycles: > 80,000
Life: 20,000 hours
Manufacturer: Müller-Licht International GmbH, 28865 Lilienthal, art.-No.: 24591
“Price: from €5.95 plus shipping (State: 07.02.2013), idealo price comparison”
Thank you, Uwe! I’m pretty sure that this assessment also other LED conversion willing very can help. Of course, although there are lots of “more noble” LED spotlights from the relevant well-known brand manufacturers. You are but often about twice to three times as expensive, and this is noticeable when eight or more spotlights in the bathroom ceiling already very uncomfortable on the account.
