What type of illumination does it have? Is it at least 50W halogen?

It comes with a 20w bulb installed and a 20w spare. See the technical specifications http://store.amscope.com/t490b.html For a brighter source I would suggest an LED model... this one is rather dull, but it is sufficient for dark field photomicroscopy

Use lumens to compare a light's relative brightness to other lights, not wattage. This light, (which allegedly outputs 3334 lumens) I'd say realistically is in the ballpark of a 150w-200w halogen light. However, this light doesn't need any CTB, has a larger surface (thus is softer), draws only 36w, and runs cool. Those are huge advantages, depending on what you're looking for. 600 LEDs. Google "cn600sa" for more info. It's a generic light from China, sold by many vendors.

It has a brightness control. I don't know how many watts its incandescent equivalent is, but it goes fairly low.

It is an LED light, No bulb. I would say it is equal to a 60 watt light as far as light output.

I think the label on the fixture says 60 watts. I used an LED 60W equivalent ( I think about 9 watts) and get plenty of light from it.

It is more yellow than the 50 Watt halogen that it replaced, however, I do not find it terribly "yellow." It is a hint less bright (like the difference between a 57 watt incandescent and a 60) and a hint more yellow, but not a huge difference.

It is NOT Halogen. It is LED, I can't say for certain if they are Cree emitters, but, it's very bright.

I didn't see actual specs on the light confirming the information, but a quick count would say about 300 leds and approximately 600w of lighting. It has a variable brightness knob on the back. I have used it with a battery pack and the power supply. It seems brighter with the power supply. Hope the info helps!

It is is total of three hundred watts between three bulbs. However I put in a dimmer not knowing it only works with incandescent liters or halogen and ow it is not as bright as I wanted. Also I thought there was an upper cover within the shade to protect against bugs and was disappointed that there was only the bottom cover.

It is rated at 350 lumen, but no where near 350 watts. Does throw bright white light. I use it to brighten small spaces such as closets or bath rooms. No where near the heat of halogen, especially during hot summer with no air conditioning.

No idea. It seemed to be about as bright as a 300W PAR56 lamp. Btw, it stopped working within weeks.

It uses a halogen T3 100 watt bulb. I bought the Philips BC100T3Q . They are not very expensive.

The bulbs do not state lumens or wattage but if I ha to guess they are 12 halogen, they are not supper bright but put off a good light source for the studio with out washing details out. Buy from amazon prime as if it does not work for you you can return it. Lol who ever I think you will be very surprised and happy with the kit.

It requires a 40 watt bulb. I bought it for my husbands desk it gives off very good light and it looks very nice great price for a great product.

It's warm. If you're worried about the Halogen-effect, you can rest assured it's not there. It's just a nice, bright light that doesn't get too physically hot. It's a very handy and versatile item to have. We love to use it to play Scrabble, long after the sun's down, when we're out camping -- without having to plug it in. :)

It does not compare to a 40w halogen. It is not as bright, and is NOT warm white! Bought 2 and one is already dead.

The only thing that I could find was this: Gu5.3 LED Bulbs, Light Lamp, 50w 60w Equivalent. The wattage seems a little high but the LEDs inside these contrallers are crazy bright. I never have mine on but my kids think that its cool.
