Help removing glass cover led

[KimG]

Calling on the wisdom of the kings of DIY #DIYwizards

I bought two of the led flood lights below.
The idea is to replace the LEDs inside.
However, there is no access trough the back. The led assembly as been put inside and then the front glass glued in place.

I'm now trying to find a way to remove the glass, without braking it. I can put the tip of a knife along the glass, but noting under it.

Is there a commonly available chemical that would help soften the silicone? Or any other technics anyone has?
Open to suggestions.
Thanks

do those little nibs on the back come off? Maybe screws underneath???

Otherwise, I got nuthin

except a hammer

Can you pry the edge up just enough to get a wire under to pull/cut the silicone? If no, you may just have to break the cover and replace it with a piece of acrylic when you’re done.

Thanks for the help guys

Not, I could not get it to lift. And I was really trying to not break the glass.
But I found a solution.
I clamped it down to the table on top of two pieces of wood, so the glass could come down.
Remove the original cable and used the hole on the back for the cable to force the glass down.
To do this I put a bolt onto a piece of woof and clamped that to the light. Tighten the bolt and hope for the best.

I was pretty sure I was going to break the glass, but somehow both help perfectly together

Thanks again for the help
