Bgsto Why? it doesn't say LiHv on the pack so why are you confused?

Bgsto Nah, Jumper don't support overly priced products from dishonest bullies like frsky

Bgsto adjustable time period using the potentiometer

Bgsto Colour temperature is possibly the least useful metric you could have, CRI is a better way to sort out cheap and nasty light sources from nice ones

Bgsto Unfortunately you need to supply your own LN2 but it's worth it for the true 650W led output

Bgsto I was thinking that they might be the brightest option too but I can't be bothered to order them all to find out. If they use the same lithium cell for each power output the voltage should sag less and produce a nicer light at lower wattage

Bgsto Working on the assumption that these are 12v LED chips I think we can safely assume they're not pulling 54 Amps from a tiny built-in lithium battery, nor dissipating well over half a kilowatt of energy in an unvented plastic housing! Ha.

Bgsto No one of these will not become a current "consumer" as someone else predicted because DIODES! Too many wannabe electrical engineers here who shouldn't be giving advice because they don't fully understand the products. In practice it's difficult to perfectly share the load between to power supplies in parallel, but it can be done (wastefully) using resistors among other methods. Search for parallel load balancing circuits.
