Dentist lamp? That's a great bench light.

Cool idea
I'm always looking for a better light. Jazz, how is the battery life? I still use cords and like you said once in a while I get a rats nest and that gets old.

About 4 hrs or so. I ended up using it so much I just bought a second battery so I can charge one while using the other.

good info, thanks. I'm trying to standardize batteries, I have so many chargers I end up using none as every battery is dead when I need it. Never have enough batteries.

If you are not away from power you can use a same voltage DC power supply for LED lights. Amp draw of most is low. Not hard to convert an old dead battery pack into an adapter (or repack into a LiPo). I have a bunch of the DeWalt 18V stuff which is now old format and battery formulation. I gutted some old battery packs,repacked 2 with off the shelf LiPo and made one into a cord to DC power supply.

Using 5-cell LiPo packs? Where do you get them? Photo of one of the battery packs before you closed it up?

18650 and 26650 lipo cells are readily avail. Most old laptop packs are full of good 18650s and one dead one. I run them in monster flashlights. I just had to rebuild an Ingersoll Rand 19V lipo pack that is no longer avail One dead 26650 cell took a $200 battery out of commission. Cost $20 to fix as I had to buy a 2 pack of the Sony cells. They were surprisingly easy to solder tabs on w/ the nickel plate (still need to be FAST w/ a big iron.)
For a non-round solution there are tons of RC airplane/car lipo packs but likely wont fit as well and have no protection. Some SCARY amounts of energy storage avail there. I have 100+Wh packs now. It is what I was going to convert the IR pack to if push came to shove. Edit: FYI, 18650 = 18mm OD x 65mm long. No idea why the trailing zero. 26650 = 26x65.

You can get protected bricks and unprotected 18650s too. Don't buy no name 18650s and don't buy ones that advertise high cap. Most 18650s on the internets are crap. I have found the best power to $ is in the brick format. The down side is you often have to mod the old pack to fit but the upside is you can use a single brick. I mod up one old pack to take bricks and then just get 2 bricks to swap into the old pack. Now I can use an inexpensive universal RC charger that charges fast and balances the cells. A 4S LiPo brick replaces old school 18V just fine in everything I have tried. YMMV.
