Bright idea for the Handymen in here

[R]

that price it'd be well worth buying 2 !

[Rod]

Anyone got any idea:

How bright is it? And what's the battery life?

[Bruce]

Probably not that bright, eh?

[Harry Bloomfield]

It happens that Rod formulated :

For the same price, I picked up a (similar) re-chargeable one with car and mains chargers. It ran for a good many hours per charge (4xAA NiCad cells) and was eye hurting bright.

Actually ther're not that bad and battery life is good - in fact I've never had to recharge mine in 2 years + and don't even know where the charger is. But not at that price - I got mine form Lidl/Aldi sometime back for about half that price.

I've got a B&Q one with 40 odd LEDS and its very bright indeed. LEDS only consume a fannyfull of power, so I guess ages.

[Steve Walker]

Is it an angle grinder?

Given that making white light from R,G,B leds is cheaper, why are there none like this on the market?

If you are a *true* DIYer...................Why haven't you already got one then? Hmmmmmmm????????????????

[Andrew Gabriel]

You end up looking at images with terrible shadowing, like chromatic aberration on steroids. If you go through a mixing diffuser, you lose some of the light, and you lose all the directional properties, and then realise just how dim LEDs are when the small amount of light they give off isn't concentrated into very narrow beams.

People have been trying to get this working for ages, because the raw coloured LEDs are both cheaper and in most cases more efficient (no Stokes losses).

[Dave Plowman (News)]

For a start you'd have problems finding superbright types that provide the actual primaries. Then you'd need a diffuser - unless they were very small indeed. And you'd likely end up with no better a result than the so called white available now.

[Andy Dingley]

You'd need it, the Rolson one is crap - dim LEDs. Lidl's (might have been Aldi) is much better.

OK, just a couple of years ago I'd have been raving about the brightness and whiteness of those LEDs, let alone the price - but Moore's Law is a harsh mistress.

[Steve Walker]

I've got a 9'er, and a 4.5'er, and a little Dremel too..... :o)

For christmas I want a petrol Stihl saw, even though I have no conceivable project which needs it.

[NT]

If you used just 3 LEDs, yes. If you use a matrix like the above light of 10s of LEDs, I don't think so.

actual primaries.

No shortage of them in the Rapid catalogue.

see above

The prices and specs in the catalogues don't agree, whether you use a diffuser or not.

[Dave Plowman (News)]

They're common in discos and TV studios as effects lights (lighting say a white back cloth, to any colour you like . And you can see aberrations if you get close to it. And they have many many LEDs.

The specs don't seem to tell the true story.

I bet that 9 footer and even the 4.5 footer is a bugger to control.

Prolly better to be ridden I reckon ;-)
