What to do with buying stage lighting from online shops

[bohan131411]

Can you help me decide among these three LED Waterproof Par Lights please?
First, I'm buying from China.

Second, my budget is 50€ max, so if you have a different recommendation please tell me.

Now, this is what I have narrowed my search:

Outdoor waterproof led par can stage lighting, (32€, free shipping).
waterproof outdoor led par can 54pcs 3W LED RGBW, (47€, 27+20 shipping).
36pcs 1W outdoor led par light IP65 waterproof, (61€, 55+6 shipping, i could not find this one cheaper).
Can someone help me with this, or if you have a better way to do it? I'm new to buy stage lighting for our events and need some help to advise where I can buy cheap but good quality lighting online for our wedding parties. I was thinking I could buy some lasers first maybe from the following site:
Is there anything I can buy in let's say roughly $100 range?
But i am not sure of their quality and warranty.

Opinions and advices are warmly welcomed.
Which one is better? many thanks for kind suggestion

Don't think you get ignored. It's just that, for example, the last time I was live on stage is more than 20 years ago, and we had two tech guys taking care of all this. I simply don't know anything about this subject.
