An 8 bulb T5 uses over 400 watts! (54 watts a piece T5 HO) I’m not sure how much your power costs where you live but here is Cali it’s ~$0.35 cents a Kw/hr. 0.4x.35x24 hours a day = 3.36 a day or 100$ a month. 3 of those is $300 a month here.
Whereas a 4 bulb T8 with LED is 68 watts. .068 x.35 x 24 = 0.57 cents a day or $17 a month, 3 would be $50 a month.
Now of course those T5’s HO’s are gonna put out more light but for 400w I would absolutely go HID.
Well that’s something to think about too. Don’t know how much extra electricity my spiderfarmer 2000 is costing me but I didn’t notice a hinge change In my electric bill. I think that is one reason that I went with that light was efficiency

3 essential tools for all growers looking for equipment efficiency is a infrared thermometer, Kill-A-Watt meter and a Lumen Meter. With those 3 and a tape measure you can see through all the B-S light manufacturers feed us.
wattage in
Lumens out
heat created
knowing those 3 things will introduce the scientific method to your grow equipment. Your results will be testable, repeatable, and have clearly defined boundaries.
Never paid much attention to it because my electric bill didn't change enough for me to worry about it. Loved the outcome of using my HOT5s though. I will still use them when I need too. Right now in growing Autos outside.
Done lost one to the god damn wind and one too a fking Mockingbird. *******.

I know the feeling brother. Really pissed me off when my two week old Gabagoo was blown smooth out of the soil. I wasn't home and by the time my Wife went to move her it was too late. Still have a baby Gabagoo and Zkittles that's okay. Moved them on the porch.

I'm loving my SF-1000 and it seems you already like the SF-2000. You could get an SF-1000 without the dimmer for Veg around 90 bucks. (I hardly use my dimmer, a bit of a waste)

I only person I know who grows has been growing for 20 yrs, he swears by 4 ft fixtures for veg. I'v seen them in veg and they grow great. He uses hps for flower
I have the 1000. I like it. I wish I had another. Some cheaper lights might not penetrate the canopy. That 2000 must be nice!
Where can you buy that for $90?
The new light has made all the difference in the world. I can almost see them growing before my eyes. I’ll bet the 1000 is a good light too
I am going to add another 1000. The one without the dimmer is on sale. You don't use the dimmer that much. Maybe for seedlings but I have some lightbulbs for that.lThe new light has made all the difference in the world. I can almost see them growing before my eyes. I’ll bet the 1000 is a good light too
I found it. Thanks!

The only real issue with that light is longevity. A thin heat sink will inevitably lead to shorter lifespan due to heat. I'm not saying it'll die in 3 months, but it might only lost a couple years, if it gets too warm then put a fan on it.
On a side note I appreciate how they tell you that it only Replaces a 200w HID fixture instead of inflating the output.
My SF2000 doesn’t really get that warm. It’s been running constantly now for almost 2 years. I have been very satisfied with it. When I started looking for a light for my veg tent I considered another SF but knew I only had my light experience to compare it to. I decided to go with the MARS2000 instead which seemed comparable to the SF. I can tell you that I am equally impressed with it and so are my vegging plants which seem to be growing fast enough to actually watch them grow before my eyes. Will be interesting to actually compare the two lights now.
Amazon has these for 76 dollars each
Buy 4 and mount them to a commercial cookie tray as the extra heat sink
You'll have a decent 400 watt light
Looks like it is a lighting deal and you can only get one for this price NV?M
