GU10 fluorescent downlighters

Postby MetalHalideHater » Mon Dec 17, 2012 3:32 pm

My dad decided to buy one, so we could compare it against the 50w halogens and potentially save energy in the house. The lamp is well made Megaman one, but when I saw it only had 1.5mg of Mercury, I knew it would probably be atrocious. Anyway, I did a test run connected to a bit of flex... and, well, my fears were confirmed. It starts off REALLY dim and pink, and even when warmed up, it has quite a strong pink hue to it. The only test now will be to see whether it will last as long as the Sylvania Coolfits that are already there that have done 7-8 hours a day for 6 years.

My bro tried some SES type CFL reflector things and actually took them back after a single night as the colour was ***** and were very dim! Oh well, I did warn him :)
My 7.5w Sylvania LED GU10's are still going strong however!

Them 7watt GU10 fluorescents are not very good, some last and some don`t, I had a problem with the wires not being soldered properly in the pins.
If you want to try LED, go for Philips GU10s, their not a bad price at Wickes.

These are 11w. When I was running it side by side with a halogen, it seemed really dim, but once in the ceiling, it is quite competitive.

My mum & dad have some of the dimmable Megaman GU10s in their hallway. Like you say they are dim when switched on, but once warmed up they're good and have lasted a lot longer than gash normal GU10. :roll:
For information the GU10 stands for 10 minute lifespan..... :D

I put GU10 Megamans in my Mum's bathroom - I regret it big time!
By the time you put the light on, go for a slash and wash your hands, the light hasn't even warmed up!! I'm going to swap them for LED soon I think!

I have a box of Megaman GU10 CFLs at work for dimmer compatibility testing (I design big dimmers).
Someone took a liking to them, and they disappeared.
They were so crap, the box full returned a few days later!
(unlike the LED ones, I have to keep them locked up!)

Yeah, they are pretty dim and really inefficient 920lm/w roughly. Are the dimmers you design PWM, TRIAC, DIAC or linear.

Hi,
They are SCR, Triac and MOSFET dimmers, controlled using DALI and DMX.

@Kev-they were the 12v halogens that were there before. They've now all been replaced by GU10 LED (apart from the megaman)

For LED yeah i can see why, the 12v driver is prone to less trouble than the 240v one. But the real damn thing i seen is the 240v 2-pin (not GU10) halogens. 240v in a socket of the same type like 12v halogens use, in a damp environment - i dont like it much
