How bright is this light (compared to 60W bulb)? 415 nm should appear as violet, do the blue LEDs have a slight purple/violet appearance?

Yes the color looks slightly purple, the product has worked well for me more so than any pillor topical agent.

The light isn't bright at all. A 60watt light bulb is 80% brighter. It comes with eye goggles. Probably don't need them as the light doesn't seem to hurt my eyes.

Seems at least as bright as a 60W incandescent bulb at equal distance from my eyes. The LEDs have concentrating lenses over them, so the effect is a cluster of magnified beams. And yes, the purple violet tint is there and I assume delivers the promised effective wavelength.

Can't answer precisely because I don't have the specs on your existing tubes. These are 3000k color temperature which is warm white not the garish blue white of higher color temps. Light output should be the same...they are both 32 watt.

The light color is close to a 6000k HID appearance. I feel that it is way brighter than a HID set up.

It appears the way a REAL blacklight should look: the blueish/purple glow. I was very unsure about the appearance when I saw these bulbs as well, however, they are a TRUE black-light and makes neon-colors POP!

830 lumen, 6000k Daylight White, NICE and bright for 60 watts! I ordered several for the kitchen, bathroom, and am considering ordering more when the cost is even lower!

These lamps are not quite as warm as incandescent bulbs, but they are not a harsh blue either. I am using them in two bedrooms and a long hallway and the light is a clear white and brighter than the incandescent candelabra bulbs that I was using. They seem to be the same color temperature whether at full brightness or at a reduced brightness.

Its what you are referring to as harsh white. Its a very high color temperature, although I dont know the exact number, I could say its about like 6000 Kelvin LEDs. And the light output is very high, brighter than my 50 w halogens which it replaced.

It depends on the color temperature of the other lights in your room. This one is 6500K, which is very cool (blue-ish). I don't personally find the color to be very pleasing for a home setting. If you have lots of warmer tones this will definitely be noticeably different. And it is obviously quite bright as well.

I just checked the actual bulb and it says 60w. Although it seems like its 40w because it's not as bright as a "regular" bulb. So if you want one that looks 40w then it's the right one.

There is very little difference in the spectrum between 660 and 630 nm so you will not be able to notice a color difference. We're very happy with these lights!

The light is LED so it's a fairly bright white, like an LED flashlight, but the cover is frosted so it's not harsh. It doesn't have a blue tinge to it but it's not a yellow incandescent-like light either. I like mine.

I bought them a month ago, and just to tell you compared to other LEDs they forsure are bright white pure 6000K. On the road, for others you'd be seen, but for you the light output on the road is im afraid of no use. I ended up switching to 35W 6000K HIDs which looked pretty much the same but with 10x more light out put, good luck :)

The light(when it works) is a bluish-purple, but it works because it emits ultraviolet light. Pure UV is invisible to the naked eye.

Mine were noticeable more yellow than my other LED's. I would put them at 4500K, I ended up not using them in my parking lights because of this.

It is more pure white. I know what you mean by the yucky blue color. Seems like the newer LED 's are going more white. This is a great light. It's on the smaller side; but puts out good light..Worth buying. The only thing I'm not crazy about is the on off switch location. Kind of difficult to turn on or off. Go for it! You will be happy.

Should be a clean bright light same as cool fluorescent bulb, not like a warm light. There can be a slight violet tint depending on contents of aquarium

In just a visual subjective opinion, it is somewhere between the 40-60w equivalent. But what I find unsatisfactory is the two bulbs I bought cast a coppery-golden hue skewing the color anything illuminated
