Thanks guys for the inputs!
In fact I've just gotten something very similar to
this
Paid S$120 each at Sim Lim Tower 2nd level. They are 1000W, can control intensity. So I got 3 of them, very compact thus good for interior shoots.
Kenny: I've tried to search B1 but couldn't find any shop selling lights, perhaps they're not open today..
So right now I'm looking for lightweight tripod for me to mount the 3 new lights.. Perhaps I should go and get those $18 tripods from MScolor hehehehhee
