First off 300w isn’t very much power —that being said if your electronics have wal wart type power supply I don’t see a problem — One problem I see is the wires and the DC plug on this unit might not handle 25-30 amps continuous use
I would like to have heard the argument going on at the desk lamp company over the wisdom of selling and shipping lamps out at a loss vs market exposure and positive reviews. 
Sorry 'bout that folks.....Mine got cancelled too.
The driver turned out to be different. Stock driver has a switch on one side, spring on the other - Quadrupel’s driver doesn’t have the spring - spring was on a separate PCB with the old classic Boruit style headlamps — oh well.
D25 style on top. Few style changes, and the threads don’t match:
So on the outside, very similar, but the inside - they combined the USB charge circuit with the LED driver on one PCB where before they were separate.

Instead of doing all that work , would not it have been easier to take the light off the headband and replace it with one to your liking ?
Deburr party for $8.

Not sure I understand. There was no work involved on this light, and these single 18650 single/dual running Anduril 2 with a nice warm LED with preferred optics doesn't exist unless modded.
No problem!
It's not your fault--you were just sharing what looked like a great deal. 
I don’t know anything about these, but I paid $9.54 after coupon and promotion. 4 lights with 18650 batteries and rechargable

That's a lot of flashlights and 18650 cells for less than $10!
I don’t see where it says cells are included.
If you look in the Q&A section, someone asks if batteries are included and the answer is yes
Check the Amazon page.
It says "It uses a 2000 mA large-capacity 18650 lithium-ion battery" and below it says "1 Lithium ion batteries required. (included)."
Anyone who missed out, another lamp for 10bux…
Clamp-on design, just the basics, but ww/nw/cw and stepless dimming and sleep-timer, too.
Code says it’ll expire soon for the day, dunno if it’ll be renewed as a different one or what, but try ISGL8IYU just in case.

I looked at a bunch of LED desk lamps on Amazon today, but I'm not looking for a clip on lamp.
Seems pretty decent, so it might be a great deal for someone else. 
Coupon stacking doesn’t seem to be working like it did before, they have added a feature to prevent people getting near free items by setting a max discount %, but I found that if I first applied the vipon coupon at checkout, then exit check out, delete item from cart and then re-add the item but now with the “save extra xx%” checked, it would still stack. But it’s been a long time since I came across a crazy good deal.
Every now and then you can get a great deal but most of the time no double hits —- might be a good thing though—keeps me from buying things just because
And in a pinch, it can block the Suez Canal!
Ordered, just because I have several new 14500 and Eneloops.
…only when it’s got that right angle 
I think I need one of these…
