They are not the same... same brand yes. Top bin diodes.... no and mixed bin is common and even cases of not the diodes claimed. Heat sinks are much better on
hlg and that's a large part of the cost.
Hlg also have much more diodes which increase efficacy and in turn lowers heat and improves light spread, not to mention should increase lifespan. The number of diodes used also adds to the cost and is a huge factor when selecting a light. The drivers may be of the same brand but often not the same quality and there are many differnt models
Infact the Scorpion diablo kills
gavita in efficacy and number of diodes nevermind the kingbrites.
Gavita does not have a built in dimmer and it's about $300 more to get it. Add to that the controller actually reduces the wattage pull from the wall.
Just to add not the same umols and they don't do independent testing... just saying
Now am I saying any of these are crap? Absolutely not... but your statement is not true and is oversimplified. So I hope that gives you some insight as to why they are not the same... because they Absolutely are not the same
