Thanks man. My first time and I must admit it's really fun. A little confusing but fun.

Just took another lux reading with my app. I must correct my initial ready as it was 46000-48000 not 4600-4800. Anyway the new readings with this app were 65000-70000 @18" @BigSm0. You were right my friend. They are pretty impressive.

Same driver and voltage so the watts should be the same?? Maybe lol I don't know it's all new to me. If I replaced the driver then there would be more current increasing the intensity and then wattage. Then I would have to calculate the heat sink? It's like Chinese lol.

It all depends on what you bought for a driver. Your at 650 ma now which is kinda low. You should be drawing 32-33 watts at 48% efficiency if you go to a 1050ma driver your wattage should increase to 52 but efficiency will drop to 44.7 If you go with a 1400ma driver wattage will go to 75.7 and efficiency will drop to 42.26. But still amazing 120lm/w

The reason why this is such a good upgrade. Saved this just for you Jupiter. University of Utah

Thats good info BigSm0! A huge increase in light.

Hey what do they know in Utah anyways lol.

I'm getting a kick out of this. A $100 first gen Mars is one thing but a current $600 dollar kind. You have got to be the first for doing this Jupiter.

Anyways yeah these cobs are very intense. Cree, citizen, and vero are on to something revolutionary in grow lighting and all 3 are competing for the next best thing. A lot of upgrades are coming out soon too. For those who don't believe in cob tech the best hps manufacturer gavita just sold 75% of their buisness.

Don't make me take apart the K5 1000 @BigSm0. I was already looking inside it... Lol

Best part is you probably think I'm super smart but I just read off the picture I posted on page 4

Check the yellow box. Those are the clu48-1812 @3500k. The first box is the driver rating which then tells you everything

 

[BigSm0]

With a 1050ma driver on those cobs you will have 100% doubled the usable light and cut the heat in half at the same wattage.

Lmao I was just scrolling back to find that. I was like I know he can't be doing all that math stuff!
