You gotta pay to see it all but this is good stuff-worth the 40$...... it seems cannabis prefers only 1500umol anyhow lol. That explains a lot of issues I've had w DE's :D
So...
Using Hortilux bulbs are like getting a lawyer.
Never shop from the discount rack. Pay the $. It pays dividends.
There's new stuff coming out every day. Yesterday an equipment broker showed me a HPS bulb that has the same lumins as a Hortilux and the almost equal umols to any of the top DE's (2100 umols). I think Gavs is 2100-2400. That's what sparked my curiosity.
The original gavita bulbs were made by Phillips just an FYIHortilux 1000w SE and DE 1960umol/s , compare with Philips DE. the 660nm red light just half. See my report

Gavita DE made by USHIO, 2100umol/s but 28% blue light rate, Philips standard 30%
Most of ther brands are from China, those DE are not real, as my report said those cheap ones just made by street lighting burner, spend same power but half effective.
Currently only my company can make it better than Philips, but those cheap ones only cost half of real one, distributors willing to purchase cheap ones to fool end users.
whazzup on Gavita de......
There is not lamp on this market that has a higher output or efficiency. The light maintenance is better than 96% per year of use, which means that after a year of use it outputs still more light than any other new lamp in this market. In our light lab, where we have a calibrated Ulbricht sphere to our disposal (the ONLY way to test light output of a lamp!) we tested the most popular lamps on the market. The runner-up was Hortilux with less than 1800 umol, so about 15% less output using the same power. Together with the highly efficient HR96 reflector we offer (96% efficiency) that is up to 40 (!) % more light compared to an air cooled reflector. So it is not strange that growers report 15-50% more yield using the Gavita Pro 1000. ROI is a no-brainier of course.

So around 1800umol. That wasn't w a hortilux ballast tho so maybe more?:D

Philips discontinued making the bulb because they didn't want to be associated with the marijuana culture.
Stole my turkey picture huh?
Lmao
You got a link or a name of the HPS your talking about? I like new stuff. The Germans make good lights- ushio is high quality. Not saying a good bulb can't be made in China ,I mean the Chinese have the second highest iqs on the planet bested only by ashkenazi Jews , just a lot of products from there are made cheaply to satisfy us cheap ass westerners. Philips is killer too! Just realized I came off like a hortilux pusha lol ;) peace

The Netherlands new law on 2013 stopped Philips supply grow light to Cannabis market. In order to avoid trouble, Gavita have to switch the supplier. But how Netherlands GOV know we buy greenpower DE for greenhouse or indoor grow? It is easy to say but hard to control it.I heard that but you can still find the green power DEs everywhere must be old stock? I'm pretty sure Gavita bought the rights which means they CANT make them anymore unless they change it substantially? I'm no patent expert;)
