Help needed! 1000 Watts LEDs on RRD-10ND - do I need a PHPM-PA?
Help needed!
So I have a client has decided to go LEDs due to the high wattage Incandescent issue in his installation - 2400 watts on one circuit.
So we spec'd out an LED candelabra bulb that will work at 25 Watts and is listed to work with the10ND.
However, I am uncertain that the 1000 watts of LEDs will work on the 10ND. The new bulbs comes out to be exact 1000 watts -
8 bulbs per fixturex25 watts=200 200 watts x 5 fixtures=1,000 watts
And I seem to recall that the LEDs draw a lot more power when ramping on. My instincts are telling me to add in the PHPM-PA anyways due to the ramp on issue.
However, it seems towork fine in the RA2 software - no caution signs pop up.
And the electrician has agreed to install the 10ND in its own box so no deganging issues there.
But I still have a nagging feeling the PHPM-PA is still needed.
Thank you in advanace - I so appreciate your feedback & suggestions!

You mean equivalent to a 25w incandescent light output? But how much power do they actually use? 6w? Usually it is a factor of 4 derating meaning 250w of leds or 41 6w bulbs.

Ughhhh! Blond moments are so embarassing. Thank you!
Yes - it would be 3.8 watts instead so 160 total. So I should be fine.
Toshiba bulb 4B11/27CF-UP
8bulbs x4 watts=32 32x5 fixtures=160

RA2-Designer-Gal, see the LED Product Selection Tool at www.lutron.com/led. The specific page for the lamps you are using is here: http://www.lutron.com/en-us/Resource...JUN%20RevA.pdf
Max number of these lamps per Lutron's testing is 39 on a 10ND, power module isn't listed as compatible with these bulbs. You can call the LED hotline at 877-DIM-LED8 and see if they have some updated numbers.

Seems weird that the older 6ND support 57 but the newer 6ND only support 39 and the 10ND doesn't support any additional.

When we tested this application, the numbers represent a consistent and steady dimming to the best performance possible with the specific dimmers selected.

Thanks for the clarification. Still surprising that there is such a big difference in the 'best performance maximum' between a hwd-6nd and a rrd-6nd.
