Not sure on the output.
It’s USB powered. I plug it into a 240v adaptor.
It has a few brightness settings, and colour balance options. I run it full bright, “white”.
Many options.
This is the one I bought.

Given its USB powered its going to be a max of 10W so about 1000 lumens max.
I just ordered a 240V 2600 lumen ringlight - hope it's not too bright.

Lumens per Watt start at about 80 for older and basic LEDs.
Newer LEDs and most LEDs currently for sale are in the 100 - 120 Lumens per Watt.
The latest research LEDs (not usually in production) are as high as 200.
Your lamp sounds interesting. You should be able to dim it if it is too bright.
Got a link to it?

I'll have to build my own housing and wire it up to 240V but that's my thing so I'm not phased by it.
I'll also measure the actual lumens and lux (lumens per square metre)
The lumens are only indicative - what matters in terms of visual brightness is the lumens per square meter (Lux)
see here https://www.woodworkforums.com/f245/...e+measurements
I already have a 2500 lux LED in the DP but it's single light and casts a strong shadow which is why I want a ring light.
Above mt mill I have an LED spot that generates 2400 lux on the spindle but again its a single light so I will upgrade that if teh DP ring light works out.
I need really bright lighting to see fine detail properly - above my electronics workbench in the house I currently have about 20,000 lumens of lighting.

I had a chance to use my drill press today in anger.
The lighting was excellent and I see no need for improvments.
Now to just see how long they last.....lol

My cheap ($14) ring light turn up yesterday - it was posted from east coast OZ but package (including instructions) is all in Chinese.
190 mm in diameter, supposed to be 24W (Ha!)
It comes with 3 small REE magnets already attached to the base that allows it to stick to any magnetic surface.
The REE magnets can also be easily removed so it could be screwed to any sort of base

For a base I cut a 190 mm disc of thin galv plate using snips and screwed it to a wooden lathe baseplate and turned a 75mm hole in the middle
To get the light to fit evenly around the DP quill, I had to cut off the mini plastic encased power converter housing (V) and used double sided tape to stick it to the base away from the middle.
I made up 3 right angle brackets (AB) from the same galv plate and bolted them to the base as shown.
A 3" hose clamp (HC) is then used to clamp the base around the quill - this means the light moves down as the bit/quill moves down, so hopefully no change in any bit shadows.

I extended the mains power cord and added a bayonet type plug ($4 at Bunnings) which plugs straight into the light fitting for the built in DP light.

And here it is fitted to the DP.

Now for some pics of the thing working but firstly the shadow cast by the old LED light.
The old (well not that old really) LED globe in the DP is rated at 14W, 1070 lumens and according to my mobile lux meter generates 277 lux at 150 mm from the chuck.
Plenty of light but the shadow is prominent
OldlightView.JPG
Below shows ring light view - only a tickle of shadow but not that much brighter.
This is confirmed by the light meter which says 300 lux. (remember its supposed to be 24W ) so not very much brighter in practice.
Still much more "even 'lighting than before which I would expect.

While I was installing it I was worried it might get in the way - and visually it does appear to block the view but its actually OK
(light is not on in this shot)

If it does get in the way it's very easy to remove and replace the original light globe.

Thanks Bob...I will also go down this road.
Shadows are a bugger.

Not a very good feedback score - maybe look elsewhere,.

Bob's is totally unlike as mine has a diffuser in it. Shadows can be helpful, I too thought I didn't like the shadow when I first saw it but I would not be without it now after realising how it can be used. This is what I bought COB 80mm LED Car Angel Eye Halo Ring Bulbs Decoration Light Rings White | eBay

Thanks - been playing around with it this evening.
As the bit gets closer to the workpiece more of a shadow does appear, which gives me the pips, but maybe like Chris I will learn to like it.

That’s good. Any chance of a pic of the shadow when using a very short bit? Say a 1.5mm?
