passion and love is a key .

We could always work a few opamps or even a microprocessor into the circuit.

I'd like to see someone build L'amp with 1500w 220v halogen sticks, like I did on my F2, some years ago...beside sounding magical, it will look magical as well...

Default Always something new...

Hi Nicoch58!!

Here is something I just spotted on Farnell - PRO-LITE - K1/110V-PROPLUS - LAMP, D-ENDED, 110V, 118MM, 500W!!!

Two of these in paralell will give app... 12,5 ohm and then you are close.

And the price = ultra cheap!

Wanna try - someone?



Olav

Interesting are the sticks sockets in your wonderful build : where did you find them ?

Hi Stefano!

As far as I remember, halogen sticks were some no-name ones, (the cheapest chinese ones I guess).
Stick sockets? Hehehe...I was scratching my head back then how to solve that one. In the end, I just bought a pair of cheapest reflector lamps (like the at the pic) scraped them and used the sockets
Also, there are some air-cooled power resistors of 75 ohms each, otherwise of no use, but I just used them in paralell with the sticks to provide a bit more current...

By the way, I was also considering using some infrared quartz heater elements instead of halogen sticks, but turned out I didn't need them... (not sure if they would work, maybe someone could try

Hi Vix !
Wonderful stuff ! infrared quartz heater ? oh are they cheap ?
By the way below there is a picture with the photo lamp that I did find here in Italy . I will build into 2 of them ( 500 watt times 2 ) plus one of 200w par channel . Building the "case " right now .
