Does somebody could comment on comparison of light brightness of this LED machine and old type lamp based Vertigo, which was using 2x 300 watt lamp?

LED light is much better light rendition. Also...get this...you NEVER have to change the light bulbs because you dont have little hands nor a sterile laboratory to make new drivers . The old incandescent bulb cost $8.00 each....so by the time you buy all the bulbs you may as well just spent the extra $30.00 to buy the LEd.Because they never get hot enough to burn out...or the fillament will be thrashed from side to side just ripping it apart rendering loss of light output. As far as brightness goes....Yes 100% brighter with tighter figures being projected everywhere. And it actually moves to the music because the heat doesn't affect the driver.

I'm not familar with the lamp model. However this one has a fantastic range. I've used it outside under street lamps and it still shows up. It also shows up on a stage with 30 par 64 lamps.

Hey Benjamin There is a side-by-side comparison of the various lamps Philips makes at the end of the listing for the HF3470. It looks like it boils down to this: The HF3470 has a replaceable bulb (what that entails, I couldn't tell you. It looks like the HF3520 must be a "forever" bulb). The HF 3470 has a "sunrise simulation" which I dig, and helps me wake up more naturally, which is what I bought the product for in the first place, so that was important to me, but is it for you? Lastly, the HF3470 has 2 sound simulations whereas the HF3520 has 5. I wouldn't call that particular facet a deal breaker. It looks to boil down to the idea of the sunrise simulation and is that worth roughly $60 for you? Happy shopping.

Yes I am currently operating the same lamp with a 300W Halogen bulb installed. Alot brighter . Has been installed for months now. Hope this helps.

Compare the life expectancy, lumens, and the color temperature. Not all LED lamps are equal. My suggestion is to buy one of each and compare. LED lamps are all slightly different. Even Sylvania has different models that have similar housings, but different lamps and internal electronics.

Yep...depending on the lamp you'll get decent performance. If you plug in a regular lamp with a regular bulb, you'll run out of time much more quickly than if you plug in an LED light. It actually has a task light on it on a flexible neck. It has 4 LED bulbs in the light and I used it to read with quite handily and I never so much as touched the power level doing so. Hope this helps!

Also luminosity is still pretty weak with solar energy. The alternative is to use LED lights. I am pretty satisfied with a 3 heads lamp post I purchased a while ago at Costco. It is very bright and consumes very little electricity. However, the drawback is that you have to run electrical wires.

Thanks y'all! I bought trial versions of the 60W-equiv. (soft white) and the 100W-equiv. ('daylight') -- and LOVE them! In fact, I'm thinking I won't be able to use four daylight 100W in my standing lamp -- that would make the (two-story, great room) living room look like a hospital operating theater!!(Oh, and John? Other descriptions say those (other?) bulbs use the "Cree LED Filament Tower Technology" to make the light be 'thrown around' like an incandescent, rather than focused like a spotlight. This 'ad' doesn't include that info -- so I didn't know if CREE used to make one without the 'circle of light.' Hence my question.) Thanks y'all! I bought trial versions of the 60W-equiv.

This might be too much light. You may want to buy a 3w as well so you can see which one give you the light you want.

It appears to me that the importer is a bit remiss in dealing with the details. In addition to the discrepancy in brightness, he also lists two different wattage ratings. I suspect that he is now selling the 20-watt version of this light, vs. the older 18-watt version, and simply botched the ratings. (1650-lumens)/(18-watts) = 91.7-lumens/watt(1950-lumens)/(20-watts) = 97.5-lumens/wattBoth of these figures are VERY efficient, and replace fluorescent tubes VERY well.

We have two of these in a 9 X 6 bathroom and they are very bright, probably equivalent to 100 watts each.The light appears to be more like 3500K rather than the claimed 3000K to me on the color spectrum. We ended up installing a LED-compatible dimmer and it worked out perfectly.

Dear buyer:Thanks for asking .55W AC ballast will brighter than 35W ballast.And 55W quality, stability are better.Thank youSean

The light is brighter than the fluorescent lamps. I replaced all my fluorescent lamps and I'm very happy. I find that removing the ballast at least for me the leds were the brightest. I hope this helps.

Hello, I own one of this lamp and in my opinion is something in-between. Originally is for biking but i use it for caving and photography in caves and I'm very satisfied. The light power is incredible and, as I use it, I never exhaust the batteries. The body of the lamp is in aluminium for dissipate the heat and it make it relatively strong. I achieved take good pictures with my camera on a tripod and using the lamp like a brush who "painted" the scene with light.

We put in a 100w equivalent led and the wattage was too much, the lights buzzed so we used 60w and it works great.

I don't know how the brightness is being figured. I do know that my first DeWalt portable light was their DW919 18V Flexible Flood Light, which I bought with the LED replacement bulb. I was very disappointed in this combination because the spot was too small and it was hard to use as a stand-alone light. I then ordered DeWalt's DCL050 20V Handheld Area Light, which has a very easy to use two-stage output of 250 or 500 lumens. This is a great light. I was sorry I ever bought the DW919 18V, which I still have.

I have used both dimmable LED bulbs and regular 60 watt clear. The lamp makes the bulbs 1/2 as bright normally. When motion triggered, the lights go to full light. It does have a photo sensor and turns on at dusk and off at dawn.
