Are these leds any good

Well, they look cool at least.. and will be decent for vegetative growth up to like an 18" plant maybe? They will not do a good job flowering at all. They're great for supplementing /using with COB LEDs. Cree CXB3590's or CitizenCLU048/58's...

Because they're red and blue man. And barely put out any lumens. Granted, they're probably better than using cfls, but not much

Hey guys quik question, i found these led lights on aliexpress for sooo much cheaper than i expected, anyways has anyone ever tried, used, tested them with success and if so whats the rule of thumb for hiw many per plant for a decent yield. Ps i found these while looking for hps lighting and all they had in relation to hps was the bulbs themselves. Also they come in different wattages from 15- 80. The 80 watt ones apparently have around 7000 lumens per bulb(light)

The 80 watt ones say they put out around 7000 lumens. To me that sounds almost too good to bed true

I agree.

The most used LED I know of is the GalaxyHydro 300. It actually uses 145 watts and puts out 7500 lumens. Considering my 175 MH bulb puts out 7800 lumens, that sounds very credible indeed. 7000 lumens from 80 watts sounds, at best, a bit iffy.

7000/80 = 87.5 lm/W. almost any LED built in the last 10 years can achieve that
