Lighting IS IT WORTH GETTING A COB LED??

[ZKJ]

Most of the online reviews on the roledro make me think they are inexpensive for a reason. I honestly think you'll be better off sticking with the Mars unless you want to upgrade to a higher end COB. I don't think the roledro will be an upgrade over the Mars.

Cheers man,what do u think of this 300w prakasa

Abit more expensive at £300

I agree. From an honest growers perspective, and someone with a bit of experience in lighting the cobs won’t be an upgrade. Cob has become popular because some are much more efficient than Epistar leds that make up a lot of these overseas panel leds. What companies like roleadro have done is taken a similar efficiency cob and benefited because of the cob hype. If you take a 20% efficient led and a 20% efficient cob you still have 20% efficiency no matter the light source. Some more expensive cobs will give you a lot more light per watt because of their 40-60% efficiency which then equals a savings on energy costs.

Cheers man how much do you think you need to spend on a worthy cob

The Autocob available from BigSm0 www.cobshop.net is a quality light. I have 6 and am very happy with their performance. There is a lot to like about the Autocob.

ZKJ - These 2 auto

plants are under 9 cobs . I was able to cut back on the number of plants due to the big gain in yield .

Unfortunately im from england so the shipping and custom charges probably make it not worth it.
I did find some on ebay in my country that look similar,could you take a look and give me your opinion.

Are you handy with tools? if so you can build a good 4 cob Citizen 1212 3500K 90cri light for < $200.00 usd. here are the primary parts. You need to add some aluminum angle for the frame and misc. wire. Look up Growmau5 how to build DIY Cob lighting on YouTube.

oops for got the cob holders from rapid led or wherever they ship cheapest.

So, I was browsing for some COB fixtures and I came across this guy in the UK who either got something really spectacular, or is trying to pull a fast one:
