Recalled A Returned Garden LED Flood Light For Restoration – Model Jack IP65
This garden LED Flood Light belonged to the hospital where I work and was brought to me in dead condition in July, But all attempts to remove the glass fit inside a metal frame using various gum removers including petrol failed and it was returned. However, I recalled this light, after having successfully opened such a light recently in July, 2024 by cutting away one side of the frame to gain access to insert a sharp knife through the side to detach the glass from the tar like hard rubber substance. It was similar to a kid ordering another ice cream of different flavor to satiate the craving!
The frame of this light was thinner and came off easily without a need to make a groove. I just plucked the side frame piece by piece without causing any damage to the glass using my beak shaped special plier. Then inserted a sharp paper knife and cut the rubber bonding and managed to detach the glass from all the four sides using a sharp edged scale. I have described these in detail in yet another article. This is how it looked after the ripping of the frame and glass:
Since I did not give a snap in my earlier article of the rubber compound that was used in this type of lights to make it 100% water proof, I am providing a couple of snaps now:
The LED board was fixed on protruding lugs instead of screws and it stayed put tightly with the heat sink compound behind. I pried it out and cleaned off the compound, then used my 1800W Hot Gun to blow away all the components.
The Mosfets were short and the LEDs were having burnt marks. So, there was no point in trying to repair this type of boards, especially when replacement boards are available at very cheap prices. Then cleaned the LED board thoroughly and fixed it back after re-applying the heat sink compound. I also soldered the AC input wires on this board along with the Fuses as an additional protection for the new two 50W boards that I bought. Then fixed the new boards on top using LED backlight fixing double sided tapes and wired them. I took care to centre these two boards so as to fit inside the reflector, for which purpose I had to cut a few millimeters of the new boards on both sides without affecting the connection tracks. The following pictures would help you follow what I did:
I applied power and was glad to see that it was working perfectly. Then fixed the glass using Fevibond rubber compound and used two to three coats of sealant on all four sides by giving time for its proper cure in between.
This took two days as the sealant needed about three to 4 hours for curing. Here is the picture of the glass after it was fixed in this way and the result:
Mission accomplished with thrilling finish, which got sucked into the collection bag! (LOL)

Nice job after fixing another garden light from the Hospital! I hope that the 50W ledboards are still decently cooled by a metal underground plate or by the metal housing that helps to prolong their lifespan.

Many thanks! The extra cooling metal bases help dissipate the heat generated and the lamps are still working very well in the garden!
