The PowerSmith 40-Watt 4,000 Lumen LED Dual- Head Work Light is manufactured in China.
Yes, you can direct the lamp heads in opposite directions.
It's not super tall but puts out plenty of light indoors and out for us. Be careful how you place them so not looking into the very bright light. Extended fully, the top of the lights is about 4.5' tall. The handle is about 8" above the lights.
It's two 20 Watt fixtures that combine for 40 Watts. I hooked it up to my meter to check and it pulls 45.5 Watts with both lights on and half that with only one one.
The lamps get hot so I wouldn't use it in the rain....I've not seen anywhere that it's waterproof.
The lights are wired together and cannot be disconnected from the main cable by design. You can remove one light from the bar they attach to, but, since you asked about portability, you can't remove one light and use it separate from the other due to the wiring.
