I want to fit one or two downlighters to illuminate our stairs to replace a ridiculous G9 bulb confection that provides little light but consumes electricity and/or bulbs in large numbers. (Halogen/LED).
It?s about 12ft from the ceiling to the midpoint of the staircase. What sort of power and beam spread should I be looking for in this situation? I?m guessing that a narrow angle beam would be more desirable here?

I have a 3 lamp pendant with individual wires that hang from ceiling mounted circular plate, with 7W energy saving lamps; the lamps are inside individual tear-drop shaped milk white shades. Very aesthetic and pleasing light to illuminate the stairwell
We have several fittings of the same type which use - or used- G9 halogens,
2 x 40W. The light was good but the bulbs failed far to often.I tried several LED versions but they weren?t nearly as bright.
Then, recently, I found these:
But what?s the bulb life like? My fitting has enclosed globes and it kills LEDS in short order.

Couple of points of information.
1/. G9 LEDS are available. They would at least last. I have had great success replacing GU10 halogens with LED.2/. What you fit is a mixture of aesthetics and pragmatics. I am running a 50W 12v fitting that now has a single LED spotlight of about 3W in it. It covers a couple of square meters of stairwell similar to yours. OTOH I have a luminaire in the bathroom with I think a 5W LED in it that because of the frosted globe/flying saucer thng is ok for the while room
- about 5 sq m
I think there are standards for lumens per square meter, that should tell you what the total wattage needs to be, after that its a question of the beam spread and number of bulbs to deploy.
And the fancy covering that may or may not fit over them
It may just be my age but even with LEDs promising long life I'd favour a solution with 2 or more bulbs rather than 1, especially for stairs.
It is absolutely a consideration.
in my case a bulb change requires a latter. Now with 12V halogens bulb life is around 8-9 years. So when after 18 years the damned thing went for the second time, although I have a stack of 50W halogens, I bought a LED for this fitting.
I've replaced nearly every light in the house now with halogens as the old bulbs pop. Apart from a couple of early failures in cheap lamps bought online, the majority have not showed any failures yet. Although all the dimmable ones don't dim very well with my leading edge dimmers.
Ive even replaced a tiny 15W bulb in a sewing machine! I don't think oven lights can take LEDS yet tho. Which is bollocks, because light pipes could easily transmit a remote bulb light into the ovens...saving all that faffing around unscrewing the stuck lenses.
I was staying somewhere that had a microwave/convection oven - that was fitted with an LED lamp. So I'd say they exist . . .
My problem is that the current fitting has very poor heat dissipation as the bulbs are enclosed in 5? diameter globes and it cooks LEDs in fairly short order. To be fair to it, it wasn?t designed for LED bulbs but I don?t want to run half a dozen halogens just for a bit of stairway illumination.
