LED recessed spotlights distances, prices

Hello everyone. I am looking for spots with about 4000K and good luminous efficacy.

Which spots do you use?
Where did you buy them?
What did they cost?
CRI value?
What distances do you have between the spots?
Satisfied?

The selection as well as the price range is extremely large. Are the expensive ones (about 20€ each) worth it, or are those for 5-10€ also sufficient or equivalent?

Thank you very much in advance!

Our electrician is installing in our bathroom five 6-watt [units], 17.45 each, in the hallway 9-watt at 22.00, on the roof overhang outside the 9 [ones] in stainless steel, 26.45 each net, prices including installation. Since he has the same in his own house, I think they are of good quality. I do not know the brand. But it probably doesn’t have to be the most expensive to be good. Ask him which he would take for his own house, look him in the eyes, Karsten

We have GU10 "spots" with light bulbs from LEDON. Just google them. When it comes to color rendering, they are among the best. Luminous efficacy is okay, but you shouldn't trust this pseudo-conversion from halogen watts to LED watts. Color rendering and luminous efficacy constitute a technical trade-off. We are satisfied, but in hindsight, we would have chosen neutral white instead of warm white in some rooms, around 3500 K. 4000 K might already be a bit too cool?

I'll just jump in here, even though for me it’s more about the light bulb itself:

Is the color rendering index (CRI) overrated, or should you specifically make sure, for example in the kitchen at the countertop or also in the bathroom at the mirror, that the LEDs have a CRI > 90?

Because so far I haven’t seen any bathroom mirror cabinet with an LED or even under-cabinet lights for kitchen wall cabinets with a CRI > 90.

Philips Hue, for example, only states that their CRI is > 80. Is it perhaps more important to find the right color temperature and brightness? So that you could also get along well with the Philips Hue White Ambiance?

What do you think or what experiences have you had?

There is a wide range of functions/features and also in terms of price. The distances are determined by the lamps, distances of the illuminated area, type of surfaces, and required amount of light. With CRI >80 you are already well served. It is better to look at how repairable the lamps are and how long spare parts are guaranteed. We have dimmable spots (3000k) from Bega with Dali power supplies and are very satisfied. But I think that is not what you are looking for due to price reasons.
