LED: 1x3w or 3x1w?

[belkid]

Hello,

I'm looking for E14 warm white bulb
but I hesitate between the 3x 1w or 1x 3w ...
Hard to say which is brighter
The angle seems to be the same ...
I am still surprised that the 1x3w has a bigger bcp radiator ... It heats more?

1x3w:

3x1w:


Thank you ;)

The 3 * 1 W have slightly 10 to 15% more brightness in lumens at the bulb level but are also more expensive generally ...

At the end of January we will make this model E14 Luxeon 1 * 3 W for less than 20 € (19.50 € probably):



Otherwise the 3W models still have 3 times less chance of failure ... well, it depends on how we see it ...

ps: no spam please I prefer to warn ...

[belkid]

difficult choice ...
pcq 3w led is never the equivalent of 20w
in compact fluorescent, there is almost nothing in spot, 7w = 25w I think ... not top either

[Christophe]

No, it's easy: LEDs for the moment are only good for passage rooms such as corridors or designer lighting for example. For the lighting of living rooms, the fluorescents are better.

If there are fluorescent spots but it is often knock.

So if you want a good economic spot E14 take this one equivalent to 50W for 9W: https://www.econologie.com/shop/ampoule- ... -p-76.html



Cheaper than Luxeons and much brighter.

Watch this too: https://www.econologie.com/economie-d-en ... -4021.html
ps: 7W fluorescent ca 35W rather than 25W (except at ike * hihihihi)

Sounds good, but the price, argh!

[Christophe]

Well that's the price ... the quality! You can compare: you will not find it so much cheaper ... if you find it elsewhere ...

Was the Luxeon price you proposed above cheaper? Let me doubt it ...

[belkid]

no, all possibilities are expensive ... whatever happens ...
but the LEDs still consume 2 to 3 times less.
I imagine that it is a bit early, we will have more choices when they banish incandescent bulbs.

[Christophe]

Yes too early is the right word because before having LED bulbs of more than 8 to 10W (minimum to have correct lighting) and at correct price (for the moment it exists such bulbs but between 70 and 100 € for 10W !!) well many kWh can be burnt in compact fluorescents!

Nothing prevents even very easily hybrid luminaires by combining fluorescent and leds on the same luminaire: 1 (or more) luxury for the rapidity of ignition and 1 (or more) fluorescent bulb for the overall brightness when hot ...

Have you really looked at this link: https://www.econologie.com/calculateur-ampoules.html because an economical bulb is investment THAT REPORTS ... what is expensive is to use classic bulbs or fluorescent bulbs of shit that flicker quickly

[belkid]

It becomes interesting from 2200 hours obviously, so 4-5 years anyway in my case (we light more in winter than in summer, average 1-1.5 hours per day over 365 days, it's for cooking).

What matters is that it is profitable
I will replace them little by little I think, as and when the old ones slam ... pcq has 17.5 euro the piece, that is quickly bcp;)

Yes, hence the interest of this calculator: make tests with fluorescent bulbs (or worse with LEDs at 25 €) that snap after 2 or 300 hours! It's instructive ...

See if it's a bulb is cost effective that's the purpose of this page https://www.econologie.com/calculateur-ampoules.html
