Recessed spot that does not light .. !! ? (scam)? ...

[r2d2]

Hi everybody

I just installed 3 recessed spotlights with a diameter of about 95 cm
after having hesitated a long time on the power of the bulbs, I opted for 12v 50w with transformer 220v 12v for each bulb, the whole is at a height of 2m25 on the ceiling in a bathroom and 60cm from the shower wall.
on the packaging of the bulbs it was written 720 lumens, 50w, 3000k hot !! ... well as much to say that it is more than limit in lighting
it lights up a bit, but that's not it .... in a bathroom
more light is needed (much more than that !!)

question, without changing everything what can I do? a link ? an idea ?

please

Maybe MR16 7W leds. Lighting equivalent to 50 W

[r2d2]

my question was rather to take advantage of the experience of people who had this problem and to have solved it, in other words that the said people saw the difference between this "pseudo" 720 lumens 3000K
"hot" which in other words does not light more than a 40 watt bulb
while I have 3 bulbs of 50w each !!
so 150w, if I had put a classic 60w lamp only it would be ten times brighter.

for your link (thank you) you tested this type of bulb?
it will not mount at home, I have gu5.3 in 12v. (Transformer)

700 Lumens, it should light up like in direct sunlight !?
I have 280 and 180 Lumens in 220 Volts, the 280 is already almost too much.

After the LEDs, it still remains quite directional lamps.
In my house there are 3 or 4 (depending on the wall) and they each light up a different direction.

Just in doubt, still check that your transformer sends 12v ... there is no reason, but sometimes ...

Just in doubt, still check that your transformer is sending 12v ...

This is indeed the first thing to do with the lights on. The transformer can very well supply 12 to 16V when empty and collapse under load if it cannot provide the requested power ...
If these are LED lamps, it goes without saying that the polarity must be checked ...

[r2d2]

the polarity check is quickly seen, or it lights up because the polarities
are ok, or it doesn't light up because the polarities are reversed
but that's not my problem ... i don't have leds! ..

I wrote above these are halogen 50w in 12v mounted on directional spots.

yes, when you look at the spot from the front it "dazzles a bit" but not terrible at all in front of the bathroom mirror, fortunately the main lamp in the bathroom ceiling light is there.

when the transformer voltage is not good, I check it is ok.

Is it a conventional transformer (ferromagnetic) or an "electronic"?
The problem is electronic is that very often they only deliver 11.5V therefore the halogen lamps illuminate less than expected (to which must be added the losses in the section wiring often limit ...)
the filament the lamps do not reach their optimal temperature and therefore light less well (in addition to last less long)

Then, the problem with halogen spots is often their lighting angle. it lights up very strongly but only on a very small cone, which gives the impression of not lighting up.
I had the problem in a room with a rather low ceiling with 3 halogen spots were theoretically sufficient to illuminate the surface to be lit, but because of the angle it did not light anything.
Less powerful LED spots but with a much wider lighting angle gave a much better result.

I will also lean towards the question of the "cone of light".

Take an extreme case:

- halogen on the ceiling
- dark floor

You have the 700 lumens (let's admit). But you light, and as long as you do not go in the beam, you have a "quasi-black" part !!!

[I'm exaggerating, of course, a little bit!]

A spot, by definition, is to send a beam of light (invisible if the air is clean) on an object that lights up and is highlighted. It is therefore the object that lights up!

[izentrop]

Hi,
Yes, this is probably a too narrow beam problem.
36 ° for halogen.
SMD LEDs have an angle of 120 °

[r2d2]

yes, it must be a story of lighting angle no doubt ....
and this story of "warm white 2900k" ...
I should have taken "cold white" 6500K

for info here is what I have in spot

when the transformer also taken in brico, I can't find it, but it looks like this one (it's a 220 / 12v60 w)

I try a led bulb with my transformer? which one do you recommend? (I keep my transformer 220v / 12v)
