California lightworks solarstorm how to#
Too bad the EVO guys don't know anything about electronics, cause they had the form factor and the heatsinking down, they just couldn't figure out how to properly drive the LEDs. So tired of seeing this crap passed off as a legitimate LED array. If they can't tell you what the junction to ambient thermal resistance is. Ask what brand the LEDs are, if they say they're proprietary like Lumigrow says. None of these growing fixtures that use fans are worth their weight in shit. and don't become a victim of some new shyster in the market. If you push 400W through 100 LEDs at 4W each you'll have more output, less heat, and longer lifetime than if you push 400W through 80 LEDs at 5W each.Įducate yourself on LEDs before you buy. It's WAY more efficient to use more LEDs and run less power through them, claiming that you put 5W of power through each LED is not something to be proud of, it means you cheaped out. The amount of power you can put through an LED has to do with it's efficiency and thermal resistance.
Ever since then the Chinese have been 1W, 3W, and 5W LEDs, mimicking the Luxeon series. This thing is just another pegged board populated with junk LEDs.Īny company talking about their "5W" diodes doesn't know shit.ġW, 3W, 5W denominations came from way back when Philips lumileds made some of the very first high power surface mount LEDs in the form of the Luxeon I, Luxeon III, and Luxeon V. Not many companies either have the ability or are willing to share this level of detailed data with their customers. In fact we openly share very detailed spectroradiometric measurement data with potential customers comparing our lights to HPS. We are very straightforward with our customers when it comes to the performance of our lights. Our SolarStorm is designed to cover a 4’ x 4’ area. But of course they do that at the expense of coverage area. Other companies need to use a narrower beam angle in order to get higher intensity at the longer distances. With our 5W emitters, the light intensity is so high, even from a distance of 24” that any beam angle narrower than 120 degrees becomes overkill. Many low end LED emitters use gel-based primary optics and acrylic secondary optics which don’t transmit light as well and lose transparency over time. We studied all the beam angle options and chose to go with LED emitters that have 120 degree polished glass primary optics.
We have a fully equipped photometric lab with NIST traceable calibration at California LightWorks. It’s simple light physics: Anytime light has to travel through another medium before reaching the plant leaves there’s a loss. What’s worse, you immediately lose up to 10-15% of your light output when you use secondary optics. external lenses) to narrow the beam angle you do get a higher concentration of light in the center but you do that at the expense of coverage area at a given height. Why are you going with the 120 degree diodes? Does it have something to do with the powerful 5w diodes you are using? The argument is that the tighter beam angles allow for deeper penetration. During the past few years it seems like companies have been moving away from these wider diodes more towards 90 and 60 degree diodes. I’m interested to hear more about your 120 degree diodes. this interview gives insight on lens angles of the solarstorm and the comapny's views on secondary optics for those who are interested.
