I need a compatible driver for a NELM-85/12/20-35-90-F LED lamp
Hello trenton.webster,
This LED has different ratings for the brightness level.
You also did not mention what voltage you are using for the supply, or if you need a dimming option.
Looking for the brighter setting, we have a few that would work with that LED.
Looking for the best priced option, without dimming, and an input voltage of 90~264VAC, you can look at part number 1866-1124-ND.
Please check the datasheets to verify compatibility to your application.
Do you have an LED that would replace a Cree LMH020-2000-35G9-00000TW that would work with a Thomas Research Products LED40W-045-C0900-D driver? The can lights we are trying to repair use the obsolete Cree LED LMH020-2000-35G9-00000TW lamp with a Cree LMD300-0040-C900-7030000 LED driver. Anything that will give us the same results as what is currently in the fixture would be much appreciated.
Thanks
Due to similarities in the datasheets/documentation I’d suspect that the New Energy products are a business unit spun off or sold by Cree, and likely to be the closest replacement one’s likely to find. The two drivers mentioned would appear to be electrically quite similar and reasonable replacement candidates on that front, though there do appear to be dimensional differences.
It should be noted that the Cree LED assembly in question appears to have been introduced nearly 15 years ago, and that substantial advances in the component products used to build them have been made during that time. Between this fact and expected performance shifts due to age, finding modern replacement components that could be swapped into an array of existing units without any discernable difference is likely to be a difficult task at best.

My concern is the MA difference between the drivers (LED40W-045-C0900-D)output of 900ma and the LED module (NELM-85/12/20-30-90-F) courant maximal 560ma.
If a candidate for a replacement LED assembly has a different operating point than the original, adjusting driver specifications to match may be necessary. In this case, a driver supplying something closer to the 560mA for which the replacement is specified would be appropriate.
A conventional fixed-range product such as the ESS030W-0550-42 could be an option, though products with switch-selectable output currents such as the LCM-60U may be a reasonable solution, and products such as the LP25W-56-PC1300-RDW that are software-configurable may also be of use.
