This is a side by side comparison of the rather impressive 660 LED lamp which is rated 40W but measures at just over 38, next to a pair of CFL lamps marked as 45W each but actually drawing about 30W each giving a total of 60W and a standard 60W tungsten lamp.
I used studio softboxes to diffuse the light and make it easier to compare.
The 40W LED lamp has camera-visible flicker, but it's not visible in any way to the human eye, even in peripheral vision.
The 40W LED visibly exceeded the output of the pair of new 30W CFLs even after they had been allowed to heat up to full intensity, and it completely obliterated the 60W tungsten lamp as you'd expect.

WOW WEE!!!!!!!! Hands down that CFL is a killer of ye ole Tungsten Lamp.
Re the lamp flicker. I found if you point the camera at the lamp, you see flicker. But when I pointed my camera at the object being filmed, the flicker wasn't visible. (I was trying one of those 'dodgy' COB leds) It may appear if doing a slo-mo shot due to shorter shutter speed. What a shame there's no link as to where to obtain this model. (I suspect it's not on ebay!)
How much does it cost?
yeah for sure gonna have to do some pinball games someday, namely have you deleted the battery holder in favor of a leak proof lithium coin cell :O
this lamp have 666 leds… are you christian soo you are affraid of the nummber? or just you did giant mistake
The flicker is in alot of cheap tvs aswell when you record to save power and in tv its make the hz look higher
6 leds missing
Anyone have a link for that exact bulb/seller?
Hiya, whereabouts can you buy such a 40W LED from? And what fitting is it? Edison Screw?
How much and who sells it?
I enjoyed your gratuitous shot.
How would the LED lamp need be modified to get rid of the flicker on camera?
Clive, I've been enjoying your clips. Curious about what it takes for a manufacturer to build an LED lamp that will not flicker, when using a camera? I purchased one and the white balance is PERFECT, but the flicker begins when you make the camera's shutter speed over 1/60 second. TIA!
I grow cacti would one of these help it grow?
What was the colour temp of the led lamp?
I am going to pose a question. What is the difference between a laser diode and a LED? OK so LEDs are more diffused but as we get ever more powerful LEDs is the differance going to become blurred?
Ha got it now thanks ๐
Ugh. That flicker would get me sick. Is it due to PWM or the AC current? Thanks for the videos!
