Not even the size of a t5, let alone t8. Only about 6 inches per light. The aluminum panels are not adjustable at all.

Shoutout to the spider farmer customer service team—they're the real mvps. Recently purchased the sf4000 4x4.

This light is excellent for seedlings as well as full grown specimens. The dimmer feature works wonders when germinate from seeds. They're very kind and courteous and i am very happy with her products.

I built a gantry style light lover to eliminate hot spots. Weight results were in line with what i’d get from a hps or hid lamp.

Apparently this led is made in korea, a seoul diode instead of samsung diode. Some are dim, and the dimmer switch itself stopped working.

Spiderfarmer is blowing me off, giving me the run around, and lying to me. Do not buy this item. Spiderfarmer is not costumer friendly!

The happy leaf light only uses 68 watts and i was running the spider farmer at full capacity 200 watts. These power surges are not acceptable for the environment. Please replace my lights with the se5000's or refund my money.

Real bummer. Kind of ridiculous. Manufacturer does not even attempt to honor a warranty. Will not fire again until it is completely cooled.
