Alzo 300 LED light

Strange, I've read numerous times about green spike, if anything I thought mine was a bit on the magenta side :)
 
My initial impression is these (RPS 200 watt) are some pretty decent lights. Well constructed they weigh about 9 lbs. The umbrella mount is sturdy. I do not see any obvious green problems, the white is very clean. Both units are consistent in color and brightness at various dim levels. The lowest dim level is about 100 kelvin warmer and the tint change is negligible. I'm going to be using these as a fill for natural light, so my sensitivity to this might be less than some people since natural light comes with all kinds of color depending on where you are.

The 200 watt version have a different diffusor than the 100 watts it appears. It is a nice removable cone made of frosted glass, vs what looks like molded plastic on the 100 watt. A foam filled protective cap locks in place over it. The included reflector is decent and does not rattle at all. It's not very thick so gentle packing is a must.

Noise wise, they do have a fan that is constant and some high pitch coil whine(?) at the threshold of hearing. Since I won't be using these near a live mic, it doesn't bother me much and I'm not sure a mic would pick up the coil whine. For $366 apiece, a bargain if the led's hold out.
 
I just got 2 Alzo (actually the RPS brand from BHphoto, same light but better mount in my mind) and will be shooting archi-torture next week. I'll report and post some findings.

I also have 3 Skylux units. The light source from them is better but I hate the ballast for moving around quickly. They might end up in the marketplace for a good deal if the Alzo 200 watt units satisfy my needs. The SKylux is a better light for shooting skin.
 
I wonder how far this can go. They already need fans at 100 watts. So what happens at 200watts? More noise and/or less reliabiity. It's great to see this technology develop.
 
I noticed Alzo has now dropped all of their HID stuff (the one and three bulbs fixtures and the bulb/ballast combo). They still sell the bulbs.

Kinda sad though. Those 800's (really about a 650 equivalent) make very pretty and clean daylight with no fan. And the bulb/ballast combo is just kickass when you need a 650-ish daylight china ball.

But sometimes the damn ballast just won't fire. Learned they're picky (and schizophrenic) about switches in-line. I also had an 800 fixture get overheated (my fault, rigged to the ceiling of a garage in the Caymans in summer, with a tent of black wrap). It died. Almost threw it out, decided to open it up and see if it had a fuse or heat sensor. There was indeed a sensor on the board, epoxied on, no breaker or reset. Put it back together and it magically worked again. Still going strong.

Looks like alzo's shooting for more reliable tech. Just wish I had a couple more of the solo ballasts, there's nothing out there for under $200 - or even close - that does the same thing.
 
What ? equivalent to a 3000 incandenscent filament ? yet only consuming 350 watts ?
That's like 30 lightbulbs of 100 watts each...
Or 51,000 lumens.
The UNIT consumes 350 watts, that means the LED(s) see like around 320 watts, as driver, electronics, fan losses etc suck up like around 10%.
So...51K lumens divide that by 320 watts gives the led lumen to watt figure of..........................drum roll please..................................................159 lumens per watt.
Fantastic, bravo, brilliant, gee-whiz, finally exists, how did they do that ?, exceptional, new technology..........
I'm gonna run out and get 3 of them right away.
I just hope it is not equivalent to a 1500 watt bulb, like I think it is.
 
I ordered the Alzo 3200 (described as a 2K equivalent) and I'm pretty happy with it. It's insanely bright, haven't noticed any color tints at all. The fan noise is definitely still present though... I was kind of hoping this model would have found a way to improve that. Luckily I mostly do music videos so I can deal with it.

I'm probably gonna get the 3300 (3K rated) one as well. It's too tempting to be able to have that kind of power for lighting large spaces, especially when the fan noise will not matter when the lights are in the distance. No more blowing the fuses! Really impressed.
 
If it's not quiter than the 3000, which I can't imagine to be the case, you'll pick up the noise - definetely no dead silence.

I replaced my 800s with the RPS 200 watt units. I think Alzo's stock of replacement bulbs has decreased in quality - I gave up after sending 3 back for major color problems. It became impossible to match the units to each other in color and brightness. The LEDs are identical and also knob-dimmable, which is nice.
 
Just took apart the Alzo 3200 unit in the hopes of replacing the 92mm fan. It's a 2pin model by ADDA: To be specific, it's the AD0912HB-A70GL. The specs are 12V, .25A, 3W draw, 2900RPM, 52.5CFM, .133 inches pressure and 35dB noise. I'm wondering what would be a good replacement. Considering this is a 2 pin model, can I use one of the more recent 3 pin fans by just soldering the connector to the red and black? I've attached some photos of the disassembled unit.P1930835.jpgP1930836.jpgP1930838.jpgP1930840.jpgP1930842.jpg
