High costs possible

What even brings me to my headline.
For a new installation, I see no problems, but should the LED floodlights are integrated into an existing circuit (gargae, workshop, etc.) you will very quickly result in high costs occur. The cable entry is suitable for NYM 3x1.5. Now depending on the common fuse a conductor cross section of 1.5 or 2.5 mm is required.
Now you have three options, replacing the fuse by a much smaller, but this may again result in larger circles problems, you drive the floodlights with a flexible conduit, or to secure the canopy separately from.
All these options are obviously a certain installation effort and thus consequential costs.

Allen "hobby electrician" out there in the country I want to emphatically suggest not "improvise" to here.
In such a case, the perception of life of the cable gland is often times left off so that IP44 lapses. Then you wonder why in wet weather the RCD or FI switches flies every now and then.

If the cross-section for the same fuse too far reduced in order to import any cable can, the line protection is no longer guaranteed.

Just for info. It is the cable which you abfackelt the booth, not the LED floodlights !!!

In addition, the cable gland is not trimmed, which can lead to damage to the insulation during insertion of the cable. The clamp is attached to the housing so scarce that when the cover screw also the insulation of the wires can be damaged, and in the worst case a Querschnittsverjünung the veins occurs here.

My Conclusion. The radiator does what he should, but can result in high costs lead to when absolutely necessary, proper installation, make to naught quickly because the favorable price.
