High CRI White LED vs CFL
Default

Well, Manu, my background is in science and engineering, albeit materials and not lighting, but I have worked with lamp manufacturers as both customers and suppliers off and on during my career, and until about a year ago, had my own line of LED plant grow lamps that were custom manufactured for me, so I am not totally without knowledge on the subject.

That said, I am not debating how bright the lamps appear, just the intensity displayed by your meter.

As to the wattage on the lamp, if they are labeled as being 10 watts, they had better be damned close to that, as they would otherwise be violating the law and putting you at risk of a fire.

Thanks for sharing your background! It helps understand who you're speaking to... I'm not a scientist and am not claiming to be an expert. Just sharing my observations about what I think seems to be a great product that could help some people in the same situation as me. I don't work for Ikea and have nothing to gain from this, just to be clear

One thing I do know is Ikea is packed with the worlds best engineers and I can bet they hired some very knowledgable people to build their new series of hydroponics gardening, lights etc. Did you perhaps consider that the bulb design could be a part of why it's so bright. Perhaps the reflectors inside are extremely efficent? Just throwing this out there...

I honestly can't wrap my head around your claim about the meter not giving a valid result. I test full sun and get the expected 10 000 FC, my CFLs read out what's expected depending on the W, even my kitchen GU10 LED Spot lights 6W 470 lumens I read below 600 FC at 12". What's so special about the Ikea bulbs that would make my meter suddenly provide false results??

What kind of meter are you suggesting I'd need to get a valid result?
