Elite 1200W
Grow Lights258W
The Elite 1200W sits in the middle of BESTVA's Elite line: 120pcs of Dual-Chip Bridgelux & Epistar LEDs, 257.6 watts at the wall, a NiuLi HLG series driver, and a comparison to a 1000 watt HPS.
BESTVA quotes 120x150cm (4.5' x 5') for both grow and flower — a rectangle, so it suits a long tent rather than a square one. Beam angle is 120°, rated lifetime 100 000h, and the auto sensing supply takes 120VAC, 240VAC or 277VAC.
The number that matters here is 257.6 watts, not the name. Over a 120x150cm footprint that is reasonable for veg and thin for a full flowering run unless you are hanging two.
