Re: New LED Work lights

Can't comment on the connection, but unless your stand is something commercial, you may find a new combination LED and stand for less than the cost of trying to find something that fits your old stand.
Big variation (seems to be improving, though) in one LED fixture that says it's a number of lumens vs another. Same with the bulbs. I think the reason isn't design, but rather fraud on some of the third-world produced stuff (just like the days when computer speakers went from 15 watts to 480 watts on the outside of the box, but didn't sound much different).
The good LED products are, in my opinion (because of the lack of follow-up shopping, or for the tubes, the lack of the need to deal with ballasts or find a waste collection event to get rid of old tubes), the best thing I've had in my shop.
