Is it possible to reduce the consumption of LED strip and how?

In view of the current situation, there is a 24v LED driver for 100 watts and 20 meters of tape for a total of 200 watts.
I want to power one from the other, but I have heard that the LED driver will overheat terribly at full load and quickly fail (is it true, by the way?). So, is it possible, for example, to connect a resistor in series, thereby reducing the consumption of the circuit to 90 watts. I'm not talking nonsense at all?)
Or is there a simple scheme for reducing circuit consumption in the public domain in the case that the main consumer is an LED strip, and the driver will produce 90 watts?

Are you afraid to connect and try or something?)))
You are really afraid ...
The driver will go into defense, or if it’s completely crooked, then it will puff stupidly ...
Miracles do not happen, there is a reserve of 30 percent ... And you want 200%
Rezyuk is yours lower the voltage and the lights just won't turn on))) Yes, and the rezyuk itself will warm up ... bash on bash
Therefore, the answer is no way

can then just reduce the stabilization current in the LED driver ??
it must contain the setting of the entogo parameter.
give pictures of the stabilizer and the wiring diagram.
apparently you have a 24 volt stabilizer and a tape powered by 24 volts, i.e. series LED set and current limiting resistor ??
then reduce the voltage on the stabilizer.

in the presence of not a "driver" but a stupid source. it's just not possible to change it. the cost of alteration is conditionally comparable to a new source.
buy from Chinese dc-dc in numbers "10a" to exit, it's better if there is an option for 15. connect, set 10V at the output, connect the tape, leave for 30 minutes. further increase the voltage with pauses for ~ 20 minutes, stopping at a moment will be very uncomfortable for the hand to hold on the source case.
also for a tape of 20 m, the length of the pieces and the scheme for their inclusion will affect consumption.

a driver for 100 watts most likely will not even give out these 100 watts, God forbid 75 without overheating, and if it is Gauss or similar junk, then there may not even be half the power. as an option, cut off a piece of tape of suitable power and power it from the existing driver, and for the remaining piece of tape
, buy a second driver of suitable power.
for good, you need to pull 2 ​​more wires with power along the entire tape and connect the tape to power at the beginning and end, or if the tape goes in a ring, connect the beginning to the end.
