The modes for this driver are in the order high (100%), medium (33%), low (7%), strobe, SOS. This means I waited weeks for a driver with modes DX claimed were in the opposite order - low, medium, high. @Janmee I'm not happy about that.

The stars allow other mode groups to be hard wired. There is no memory, so after a few seconds off it reverts to high.

1: Default group, star already connected to ground.
2: High (100%), low (20%), strobe.
3: High (100%), medium (33%), low (7%).
4: High (100%), low (20%).

That 3 mode non-flashing group would have been great if they had been in the advertised order, coming on in low and giving me the option to increase the output if I wanted more light. When I use a multi-mode light I almost never think "oh, I have too much light; I could/should turn it down". However I do very often think "I need more light, I want to turn it up." With drivers like this I have to cycle through the modes to find the right one and remember where I am in the order so I don't end up using a brighter one than I want. STUPID!

Edit: My current measurement for low in the two mode group was 20% not 10%.
Edit 2: Taken some more measurements, the low in group 2 is also 20%.

Sorry but we don't ever change this sku's description.

I'll open a ticket for a refund then.

But I checked the history record, there is no any modification for this SKU.

The last time I tried to order one (add it with DX points) it was sold out. Is this a new batch? The programming could have been changed.

What do I mean "could"? It has changed, assuming it was originally as claimed. It could have changed then, with the new batch.

....forgive me for interrupting gentlemen,

....would either of you enjoy a cup of tea?

may we all live in an experiential place :)

Tea, huh? Chch is rather an English city. This was the driver I mentioned I was expecting. Sigh.

... i so know i've got at least 1 soic-8 clip somewhere.

it is joy to handle pcbs as well made as this one pictured.

If only it was programmed as well as it is made.

(Hey, how would you expel gas inwardly?)
