Indoor Feroled 357 LED v HID 250w dual spectrum

[Red eyed c]

What brand to buy? It depends how much you wanna spend mate.obviously a lot of members use blackstar as the price & power is good value.if you wanna splash out check out the penetrator gen X series,Seymour uses that line and if i had the $$$ id own one too..littlebps led also looks and performs well as you can see so the choice boils down to money.not sure who has the longest running led,with this tech being new I don't think anyone's owned and used one for like a 3-5 year stretch,but if you buy from a good company they offer good warrentys,as much as 3 years at some places

lbp, great experiement i liked the way you upped the wattage on the led to even out the wattage. very fair! and the results were expected. hid lighting is the old tried and true method, and there will always be discussion on witch is best. for alot of small growers the hid lighting is cheap to start up with, but when you take into account all the costs with hid, i dont see any savings because of the heat produced requires more gear, the huge difference in the cost of electricity between hid and led i ran for 5 months on a 20/4 scedule and the cost of 385 watts of led was about 8 bucks a month! thanks again lbp! if i can ? +rep

mix might be the answer for me as I need the heat in the winter, without it I would be running a heater...

I've had my GLH for a year and a half now. They were one of the first 3 watters on the market. So far, it's been great. Had a driver go bad and they sent me a replacement plus a spare. Four screws to remove the cover and plug and play replacement. 5 minute repair.

Most are rated at 50,000 hours, almost 7 years running 20/4.

cool so who's got the longest running led? and what brand to buy the prices are all over the map...

I ran HPS before switching to LEDs. I run a small heater in both my areas. I've found it easier to add heat than take it away. Temps are much more stable, especially in my outdoor box where I'm drawing fresh air from outdoors. Inside it only runs about 1-2 minutes every 15 minutes or so.

I got a humidity problem also so I get heat from the dehumidifier that runs when the lights are off...

and the 3x4 12 sqft area ? for a 300w you find thats right on?

the impression I got was the higher they drive the diodes the shorter the life of the system but lol maybe someone else can explain it better

 

[astronomy420a]

here's my 2cents it is true that a 3watt diode will not live as long, driven at 3 watts, thats why the manufacturer claims higher watts than they draw.
example i have a blackstar, manufac. claims it is a 240watt unit using 80 3watt diodes, the actual amperage draw is 175 to180 watts simple math tells you that they are driving the diodes at 66% . another factor in the life of a diode is the lens degree, 40deg.,60deg.,90deg., qnd 120deg using the same diode, the life will be shorter on the diode using a 40deg lens than a 90deg lens, because of heat witch will increase with a tighter lens degree.

Wait so your 240w blackstar is only drawing 175-180 watts. Thats fucked up

Yeah that's true,but look at what muddy says on previous page mate,only 15% of hps light is useable compared to 95% with LED,there 80% more efficient at giving the plant the correct light at a lower cost
Most companies do now list the actual power drawn which the didn't used to do
